Breeders is a simulation of artificial life driven by physics and simple rules. It's a sandbox for exploring emergent behaviours, tinkering with ecosystems, and exploring the stress relieving effects of tossing around large numbers of bouncing boxes. :)
A quick look at my first morphing mesh tests with Mega-Fiers. Amazing tool! It lets you morph between mesh shapes - and combine a dozen other ways to fold, spindle, and mutilate meshes in realtime. I should be able to use this to make growing plants and some stretchy critters. :)
