Past simple

And you should really just go look at Golan Levin's

And different artists that I've mentioned,

Then I made this video, which I actually kind of love

Just using like a nice little math formula.

It's time to make a GIF loop of the heart

It's Valentine's Day, this is what we're doing.

Alright, so first that I need is for this

Which is that, if what I'm doing is I'm adding these,

I'm adding the vertices of the heart over and over again.

is start deleting the ones from the beginning.

So I should go back to that idea of percent.

So let me actually open up my other thing.

So I'm going to open up the GIF loop code.

And I'm going to put it in the render function.

And now the percent, the percent is going

A equals map, percent, which goes between zero and one

This should just be, I've got my GIF loop.

Let me just move everything out of the way.

I've got my GIF loop here and I want record default.

I mean there's a bunch of things I could do.

if I record it, I mean in a way I'm getting a loop,

but I want it to like shrink back down to zero.

So basically I want percent, I want this to be like,

actually when percent is between zero and .5,

halfway through. I want to draw the heart.

But if percent is greater than .5, is less than .5,

There's probably a better way way to do this.

But I'm going to do it this way right now.

Otherwise, I want to remove the number of points

And I think it actually is just going to work

if I just say heart dot, how do I delete something out of,

I should make, add some colors and things.

Okay, okay, we're going to add beating to it.

the size is being controlled by this thing, r, here.

So I can control the size here just while I'm drawing it.

Great, so now what I want is the r to be,
