Try this (incredibly frustrating) rock stacking simulator (neal.fun)

Feature request: Don't reset moment and momentum when released. I want to spin and fling them :)

You know, by simulating collision with simple AABBs you could improve performance a ton and make me far less frustrated. ;)

I hit the link and gave my phone to my partner. She handed it back a minute later and asked "Does this count?"

Damn; this is the most zen rock flattening simulator I have ever used.

Nice I did it https://imgur.com/a/CHINNfb

Why do the rocks clip through each other?

The intended use case is a replacement for Captcha

Very cool!

It would be really satisfying if it could detect a balanced stack, show some kind of effect, then offer to restart.

Maybe the restart would just replace all your rocks with different ones, which would cause the stack to fall?
