Full Transcript

Gemini 3 is a really really good model.
We were able to create things like voxal
art generators, ray tracing simulators,
golf swing analyzers, orbital
simulations, and a custom Monopoly board
game generator. Let me show you. So, we
took the Voxil Art generator provided by
the Gemini team at launch and we made it
our own. So, we continued the chat. Can
we rebuild this but procedurally
generated robots as voxels each time? We
had to go back and forth just a couple
times to get it right. But now, check
this out. We have a beautifully
generated voxal art robot generator
thing. And of course, you can scrap it
and get that amazing physics simulation.
Reassemble it into new random robot. And
there we go. And let's scrap it again.
Check this out. You can reassemble it
and you can make it into basically
anything. So into custom and then let's
say retro Polaroid camera. I don't think
I got the colors right, but it kind of
looks like a Polaroid camera. I I like
that you can also see the shadow on the
ground. And if I scrap it, it shatters
and it's such a satisfying animation.
So, we could do new random robot. So,
there's one. Scrap it. Reassemble. New
random robot. And there it is. Up here
are your blueprints. You can import JSON
with the blueprint. You can generate a
new robot or you can ask Gemini to build
something custom. Over here we have a
play and pause button for the spinning
animation. And then you can also export
the JSON of this voxil. Look at that.
Beautiful. Here's another one. Let's
scrap it. Reassemble into new random
robot. Now, each time you do it, it's
going to keep the same colors as the
previous time. So, if you just refresh
the page, then you get new colors like
so. And there we go. A new robot with
new colors. And by the way, I'm going to
drop all of the links to these that are
sharable down below in the description.
And by the way, if you want to learn how
my team was able to create these
incredible demos, definitely download
our free humanities last prompt
engineering guide updated special
edition for Gemini 3. I will drop a link
to that in the description below. You
just need to sign up for our newsletter
and you can download it for free. Go get
it right now. Next is a ray tracing
demo. Here's the prompt we used. I want
to create an app that showcases 3D ray
tracing of metal textures. I want to
create basically a walkthrough house of
mirrors where you can move the camera
slowly through the house of mirrors and
it shows a voxil man in high definition.
Make the voxels look really good so you
can see the voxels in the mirrors. All
right, let's stop there. Let's see what
it built. All right, so here it is. You
can see the ray tracing in action. You
could see the reflection in the mirror
right there. You could see the little
metallic pieces floating around. There's
the voxil man in the middle. There's
some artifacts as you can see there, but
the reflections really work well. The
light is definitely bouncing around the
room and it's running decently well in
my browser. So, look at this. We can
move all around the room. As we're
moving around the room, we can actually
see the reflections. Now, these lights
look like they should be coming from
right around here. There are the three.
And look, it's definitely not perfect,
but I think it's really good. Look at
this. Look at the side of this
reflective wall right here. And as you
move, you can actually see the lights
reflecting on the two surfaces
correctly. Look at these little shapes
floating around. And as they're
floating, you can see the light
reflecting off of them. Next, there's so
much talk about AI bubbles. We actually
had Gemini create an AI bubble and
research storyboard. Check this out.
First, let me show you the prompt. You
are a macroeconomist trying to inform
the masses. We are going to do deep deep
research on what financial bubbles are.
The ones that have popped in the past.
We want to understand differences
between speculative bubbles and bubbles
with lasting infrastructure. What leads
to bubbles causing permanent harm versus
realignments that create more value than
bubbles did damage fiber of and we give
some examples and please gather all the
necessary infoing the data we need to
complete our work including any
analytics we need to conduct. Okay. So
let's take a look now. So first we have
an intro interactive macroeconomic
analysis of the AI boom. Here we go.
Capex 2025 405 billion up 42%. Nvidia
margin 76% abnormal energy use phase
euphoria. All right, let's look at
history echo. So here's Nvidia 2025 and
Cisco in 2000. Oh boy. All right, here
are the Minsky cycles from hedge to
Ponzi units. Then we actually have a
bubble simulator game built into this
website. So here we can play around with
it. We could say build infra minus 25
million. The chart updates
automatically. Turn two. Let's say we
raise some money. Let's say we raise
some more money. We need to hire, of
course. So here's a few 10 millions.
Easy peasy. We're going to acquire a
company or two. Here we are. The hype
grows. The risk valuation cap increases.
But no, we're going to raise some more
money. Uh-oh, we're at 100%. And demo
day bubble popped. So, here it's kind of
a fun little AI bubble simulator game.
Here we can see the ROI gap. So, in red
is the capex, green is revenue. We
definitely want revenue to surpass
capex, but of course it's very early
days, so that's not happening yet. We
have energy standard search.3 watt hours
AI generation 2.9 watt hours and verdict
productive bubble infrastructure
survives speculators die banks safe
stocks at risk tech boom that is AI's
own assessment of the AI bubble risk all
done very simply with Gemini 3. And if
you want to take the power of Gemini 3
and other Frontier models and automate
your business, check out the sponsor of
today's video, Zapier. Zapier just
launched Unified Copilot, and it makes
it dead simple to automate your entire
workflows. The Zapier UI is already
easy, but they went ahead and made it
even more simple by allowing a
conversational interface to just
describe the automation you want built,
and it does it for you. So just type in
what you want and Copilot creates it for
you across Zaps, tables, interfaces, and
agents all at once. Copilot understands
the context across your entire Zapier
stack. Plus, they added human in the
loop so you can make sure that you're
checking in at the vital points of your
workflow creation. Zapier also rolled
out 30 plus new integrations including
Perplexity, Mistral, and Cursor. So,
with over 8,000 apps and integrations,
enterprisegrade security, and fully
managed hosting, Zapier makes AI
automation accessible to everybody. And
by the way, if you want to use this
workflow or other workflows that we have
created, I'm going to link it down below
directly to Zapier. You just click the
link and it'll set it up in your
account. So, check out Unified Copilot.
Thanks in advance. Now, back to the
video. All right. Next, back to Voxels.
We just love Voxil so much. Let's take a
look at this. This is an image to voxil
assets. So, here's this little cat
image, which you can see here, and it
converted it into this 3D voxil thing
that I can play around with and
manipulate. Very cool. Here's a cat with
a little jetpack. Here's another one. I
think this is a cherry tree on a
floating island. And I just think this
looks so beautiful. Look at that. And
then here's another one. Very cool. And
then you can also upload your own
images. So, here's a very famous
Muhammad Ali photo. Let's generate
assets. So, here's the prompt that it's
using to ping Gemini to generate the
actual voxil art. So, I have provided
you an image. You're an expert 3D voxil
artist for video games. Your task is to
generate three distinct highresolution
voxil assets based on this character
object. And we define the different
poses, the output formats, and the core
requirements for each file. This takes a
little while, maybe about 30 seconds.
And then this generates you 3D voxal art
based on the image that you provide. So
Gemini takes this image, analyzes it.
Remember, it's not that simple to just
take an image, a flat 2D image, and then
convert it into 3D voxal art. You have
to actually determine which part of the
image you're going to take, and what are
you going to represent with voxal art.
So check this out. Kind of simplistic,
but I think it's actually really cool.
So you could see Muhammad Ali right
there. Here's another version. And the
third version, and of course, you can
download any of these in GB. All right.
Next, let's build a simulator for a
large particle collider. I want to build
a super aesthetic pleasing simulator for
a large particle collider complete with
real physics sims. The idea is to
demonstrate to someone what it's doing,
but to make it super exciting with
particle effects, etc. that adhere to
your understanding of physics. Maybe
some kind of plasma sim for tokamax or
something. All right. And here it is.
So, we have a tokamok and a collider.
two different ones and we can actually
see simulations of these. Obviously, it
runs very slowly in my browser, but
that's because it's doing a lot of
calculation. Now, on the right side, we
have the AI analytics terminal, but we
actually ran out of API call quota. And
so, before it would go back and forth
and actually tell you what's going on
and analyze it and give you an analysis,
and it was really interesting, but right
now it just says connection to the AI
core is unstable. All right, next we
have a power of 10 animator using nano
banana. Check this out. So make a power
of 10 animation with nano banana and it
created it. Let me just show you what it
looks like cuz it's hard to explain. So
here we see the solar system. We see the
size scale over here. And if we forward
the timeline,
we go in, there's Earth. We continue
going into Earth. I don't know why
there's a hand there. We have a hand
holding what looks to be a cell. And
then we go into the cell.
and so on and so forth all the way down
to the smallest unit subatomic scale. So
definitely far from perfect, but it's
actually prompting Nanobanana to create
multiple images on this time scale and
then putting them all together in a
really seamless way. And you can select
what you want to actually show. So we
have universe to atom, human to DNA,
data center to silicon, satellite to
street view. Let's try that one. And of
course, you can also do something
custom. So here we go. Calculate and
generate parameters. It just takes a
minute. Okay, after just about 30
seconds, we can start it. Here we go.
Earth. Zooming in. The United States. I
don't know where that is. Here's a city
and all the way into the city down to a
single building. Here's a single street
and a storefront. So, again, like not
exactly perfect, but fun to play around
with. All right. Next, we're going to
build a gravity simulator. And this is
really cool. So interactive and body
gravity simulation build a fully working
physics accurate simulation of a solar
system style environment where objects
follow Newtonian gravity. The simulation
must allow users to dynamically add new
planets or moons specifying properties
like mass, radius, initial velocity, and
position. When new bodies are added, the
system should automatically recalculate
and update all gravitational
interactions so orbital paths evolve
realistically based on mass, proximity,
and initial conditions. So, here it is.
Physics accurate. And you can see
they're all going around the star in the
center. We have a bunch of different
settings. Obviously, you can pause and
resume. And if we just click and drag,
we can add different entities and see
how it's going to react to gravity.
Actually, this one just collided with
another planet and combined with it.
Let's try that again. I'll do it where
it goes right next to the star in the
center. And there we go. And that's
going to affect all the other planets
and stars orbiting as well. We can also
go ahead and click this to add a rogue
star. There it goes. Let's do it again.
So, you could see how it kind of
adjusted its trajectory as it got closer
to the star in the center. We can do
different things like a black hole
instead.
And we can see obviously the black hole
is going to suck in everything in this
solar system. I'm adding a planet. It's
going to go by the black hole and of
course it just gets sucked right in
here. Now this star seems to be orbiting
the black hole and eventually it should
fall into it. We could do a pulsar nova.
We can do terror life meaning basically
a bunch of earthlike planets and then
finally it explodes. So a lot of fun
things that you can play around with
here. All right. Next we're going to
build a golf swing analyzer. And so you
upload a video of your golf swing and it
will analyze it and give you a bunch of
information. a bunch of tips. Here's the
prompt. Allow me to take a video of a
golf swing and video and or the model to
do segmentation on the video. Then deep
analysis of the golf swing and then give
suggestions on what the golfer can do to
improve and how it may impact their
game. Also draw comparison to other prog
golfers and their swings and images of
those golfers to click on and see a
comparison. So here's what it came up
with. swingpro.ai.
We'll select a video. Okay. Uploading
somebody's golf swing. This is not me.
Here's the video.
Okay, pretty nice golf swing. Start deep
analysis. So, analyzing swing. So, it
says connecting to Gemini 3 Pro preview.
Then ingesting video frame data. And
remember, because it's Gemini, it will
actually ingest frame by frame, which is
a huge differentiation to any other
model on the market. Gemini can actually
read videos. And here we go. We have a
78 out of 100 swing score prolevel
analysis. This represents a highly
functional control oriented golf swing.
It gives us some tips on how to get
better. We have a tempo ratio, shoulder
rotation, hip rotation needs improvement
and X factor stretch. Here are the
things we need to address. And it's
saying we are kind of like John Rom and
Steve Stricker. So, if you're into golf
or really any sports, you can create an
app that analyzes whatever you're doing,
whether it's a golf swing, a tennis
serve, anything. Next, we have this
really simple hand tracking plus fluid
dynamic simulator. Watch this. So, I put
my hand up, I can put my second hand up,
and I can move them around, and it
tracks it and does some cool stuff. We
can also change what the actual
particles are doing. So, just like that.
That is void singularity, it says.
Here's cosmic energy, glacial shard. So,
I don't know, a lot of fun. All right.
Next, we want to do an Earth simulator.
So, check this out. Make a perfect 3D
representation of Earth in the globe
with a layer above it for atmosphere
that looks like clouds that interact
perfectly like clouds. Use 3JS and other
packages to make it look perfect. Add a
bunch of sliders that can change the
weather. add an AI enable prompt window
that allows you to prompt like natural
disasters, have a timeline along the
bottom that can speed things up and so
on. So, let's give it a try. And here it
is. Look at that. Pretty good. Can
rotate it around. We can see the moon
right there. Here we can change the sun
position. Here we can change the CO2
levels, the clouds, the temperature, and
we have different layers. So, there's
the temperature, the weather, and
satellites. and all of the satellite
paths are calculated and it looks really
cool. Next, we have a dot matrix image
converter thing. And I don't even know
how to describe this, but it's really
cool. Check this out. So, I uploaded
this image that I took around the Bay
Area and it converted it into a dot
matrix that we can do some cool stuff
with. So, check this out. So, if we
actually play the timeline, look at
that. We can actually rip apart the
image into all of the different dots
from the image. Look how cool that
looks. And then they're just all
floating. We can also do it in different
ways. So here's a pull effect instead.
We could put it back together. Of
course, we can change the effects. Okay,
that's called data glitch. Let's do
event horizon. And all of this is
calculated in the browser. Here's
quantum.
So cool. Helix
implosion.
And we can reconstruct it as well. So,
let's play.
Boom. And then let's replay it one more
time just to show you. And so, yeah, I
think this is awesome as well. And check
this out. We have a custom Monopoly
board generator. This is a fully
playable game in which you can describe
the theme of the Monopoly board. Now, in
this one, I did Donkey Kong. Again, it's
not always perfect, but if you continued
working on this, if you continued
building it, it could be really cool.
But watch this for now. So we have the
board. We have each of the pieces which
are Donkey Kong themed. Here's Donkey
Kong Express, the trains, Donkey Kong
Sky Rail. We have all the prices. Dice
roll. You can even have AI opponents in
which you can chat and negotiate. You
could say, "Okay, I'll let you go if you
land on my property next time and not
have you pay me and you do the same."
You could do stuff like that. You can
trade with them. It's pretty cool. So,
here are the different pieces that we
can move. We can buy and end the turn.
And so, now all the other AI is moving.
They're buying. We can see them moving
around the board right there. And yeah,
I mean, this is just incredible. And so,
that's it for today. If you enjoyed this
video, please consider giving a like and
subscribe. and I'll see you in the next
