There's a "game" called Critterding, which was passable at evolution and stuff, lots of knobs to manipulate the creatures and environment. Then someone made another version called Critterdrug which adds a "shared canvas" that all creatures can see and manipulate if they want/can.

I'm hoping that some day the source code is released, i've talked to the critterding person, but they don't seem amenable to it. Critterdrug is probably my favorite evolutionary algorithm example.

I'll never be able to do the game(s) justice, even if i link a video of the shared screen.
