breveCreatures is a screensaver that simulates the evolution of virtual creatures in a physically simulated 3D world. Beginning initially with random creatures, the screensaver uses a genetic algorithm to develop creatures capable of realistic locomotion behaviors.

The concept and algorithms implemented in breveCreatures are based on Karl Sims' seminal work, "Evolving Virtual Creatures".

It's a shame there isn't a proper app of this, with a bunch of controls and options, rather than just a screensaver. I have wanted to evolve block creatures ever since I saw the original program on PBS.

Its amazing how sophisticated these creatures get after about 80 generations.

I would definitely recommend this to everybody

Looks great, works great, but I can't reset. Clicking the button does nothing. Had to delete .plist file.
