I watched it for an hour, and at some point the black ball crossed the boundary onto the black side, so eventually the whole circle became black.

The cool thing about this is that it's self-balancing - if either side gets larger than the other due to random chance, the ball in that side will have more space to bounce in, and therefore bounce less often, slowing its growth. Meanwhile, the ball in the smaller side will bounce more often in its smaller space, making up the ground.

Some people here were asking for it so I quickly vibe forked a speed control slider for farming some karma here on Hacker News:

I was cheering on the black circle's tunneling project when they both got caught in a rapid-fire spiral and the black one glitched through to the other side.

An excellent piece of artwork! Really captures the meaning of Yin Yang, at least to me.

You can press 'p' to show the points on the curves.

  function keyPressed() {
    if (key === 'p') SHOW_POINTS = !SHOW_POINTS;
  }

Got a horseshoe shape running at 50x for 60 seconds:

I guess it’s supposed to start on mouse move (based on skimming the source code).

On a phone it doesn’t seem to trigger unless I changed the background so I spent a minute just staring at the symbol without anything happening lol :D

reminded me of this one that ends at some point

I made a game on this principle many years ago. Two players with turn left,turn right, thrust and fire. You can only exist in your own space, shooting at the walls dug holes of your colour.

You had a bunch of critters scattered around the map trying to get home and you had to make paths for them while stopping your opponent from getting their critters home.

$10 on black

so simple yet so deep!

anyone willing to provide a math-proof like argument on why the shape seem to stick to the YY curve indefinitely as the "eternal" name suggests?

Should it always be this way or is there at least one bad initial bouncing configuration for which chaos can take place and we loose the YY curve?

Does not seem that obvious to me.

Cool! It would benefit from better physics though, maybe supersampling the position in time especially when moving fast. Each ball can't push to its edge fully, for instance.

Shouldn't each circle be pulling in its own color instead of pushing the other one out? Right now it looks like they're expanding the opposing color, when you'd think they'd be rooting for themselves.

Sometimes I see the 'border' move slightly where a ball hasn't hit it. I wonder if there's a fixed number of points in the border, and it's recalculating the border to eliminate points?

That is so cool! That is art in motion and a philosophical statement. Well done, man! That is beautiful and brilliant.

I’m really keen to see what this looks like after significant time but I’m not going to leave it open on my phone for ages just to find out haha. Clever idea!

I want to see a real world version that uses one of those magnetic sand sculpture tables. https://sisyphus-industries.com/

Raava and Vaatu made into a game of dual-solitary pong

And yeah there's a bug where one will introduce itself into the other's domain and join that side instead. Very life-like :)

Similar to Pong wars: https://pong-wars.koenvangilst.nl/

To speed it up, run

['whiteBall', 'blackBall'].forEach(color => { data[color].v.x *= 5; data[color].v.y *= 5 });

In dev console :)

I'd phrase it "eternal adventure".

Does some interesting things if you up the ball speed to 20. The boundary breaks down.

  data.blackBall.v = data.whiteBall.v = createVector(0, 20);

Cool now I'm not going to get anything done. Thanks OP. PLEASE add a speed control so I can speed it up to it's logical conclusion and move on with my day.

It doesn't seem right that the light in the dark furthers the dark and not the light.

What happens at the limit of infinity!

What would a 3d version of this look like?

Something similar was shared before, but it wasn't this shape, just plain old rectangle style.

Are there any initial conditions that converge to a line?

Is there any interesting mathematics associated with this system?

You can press P to toggle the edge point visibility.

was browsing through source code, you can press `w` to increase speed and `p` to show points around the edge

Time to sink multiple hours a day to this,

nice. tell me that was dreamed and vibe coded over a cup of coffee and I will believe you

The most self evident piece of work/art I have ever seen and yet there's so many comments explaining why it works and how it's interesting...

Now that we have the simulation, what is the closed form solution?

I have achieved enlightenment.

Manicheanimation

what's the matter ?

Simply amazing.

It's cool.

It would be better if there was only 1 kind of edge instead of 2.

I refer to the broken edge and the circle edge.

I cant perfectly cause i dont know how to control. . I dont have any loptop for use to creat it. I use my phone

I laughed really hard at this :)
