I zoomed in and the solid walls are actually made of smaller segments. Considering other shapes are shrinking over time, I assume the same for the wall segments.

Also the visual size of the balls looks to be bigger than the physics-constrained actual size of the balls.

True. It seems like there's some difference in friction/resistance, maybe these barriers are projecting a pushing force outwards rather than being solid walls (which is a common shortcut since actual solid physics walls are hard to program) and the speed/impact/collision of the balls is just overcoming the push force of the walls.

Proving once again, that I will watch anything for 2 min

I stuck with it because I was convinced they would spell something funny, when they've reached their destination.

I’ve thought about adding some black hole elements to do this! Maybe I should. 🤔

You did your best, amber :(

I wonder how cryptographically viable this is as a random number generator, disregarding the obvious performance issues and only looking at the distribution and security.

Each ball does have a slightly different friction coefficient. I can run the simulation multiple times and get very different results each time.

Rng is basically solved already, no need.

As implied by 'disregarding the obvious performance issues' this was a question of pure curiosity rather than practical applications. Wouldn't it be funny to write a comically convoluted RNG library based on physical simulations?

I think cloudflare had a room of lava lamps that served as an rng at some point
