Chaotic Pendulum aims to take the physics of gravity and show you how that force effects different connected masses. It’s quite fun to play with, one of those endlessly fun websites that has some science attached to it, but is really just a useless game. I spent some time making some pendulums. The sharing tool doesn’t seem to work because no matter what I do, I always get a pendulum that starts out different then the one I made. Oh well, randomize it anyway.
