This is a little experiment with box2d (actually Jonas Wagner's box2d2-js). I mostly just wanted to see how easy it would be to set up (quite easy). I was also curious to see if it would be a viable replacement for the physics engine in my little rocket game. I've been using my own homebrew physics for games since I was 12, but I thought it would be nice to branch out and try something a little more sophisticated.
So, I made some long, skinny boxes (vaguely rocket-shaped) and let them loose. This looks promising, although it runs pretty slowly in Firefox on my old Windows machine. Maybe this weekend I'll make a toy rocket and see how it goes. Meanwhile, I'm mesmerized by the falling pasta. :)
