Gosu with Chipmunk physics
Gosu is a super-easy 2D game development library with a handy Ruby interface. Chipmunk is a fast 2D physics library, that plays nicely with Gosu.
Mix them together and what do you get? Me having a great time making little blocks fall from the sky:
The Chipmunk Ruby documentation is a bit lacking, but it follows the C interface closely enough that I’ve been able to pick it up without a problem so far.
