i wrote an article for java.net recently about my project, where i evolve running creatures: ;D
Checked it out … very nicely done, I like the look of it. Okay, for my game-developer eye a skybox is missing 
Of course, the graphical stuff is only a sideshow in you kind of work, the spring model is where the cow flies (as we like to say here in Austria).
Question: What are you going to do with it, any plans for the future? Perhaps do a little “Creature”-like entertainment product, read game?
Cheers

thanks!
it was really exciting to see the evolution of these creatures happen overnight. usually the surprises we get from our computers are malfunctions, but these were positive surprises. 
it’s a remarkably straightforward algorithm.
it’s true that the graphics are not core for this, but fast graphics is the only way i can make the elastic interval model accessible to people. now with the running creatures it seems that everyone intuitively understands and appreciates it.
what i would like to do with it is create darwin@home (like seti@home) so that multitudes of computers can evolve creatures in parallel. this would allow exploration into other dimensions of evolution beyond only evolving movement, like growth, or hunting/fleeing behavior. with a distributed computing based ecosystem, it might be possible to evolve creatures that are hard to kill in a gaming context, for example.
if you see potential for collaboration, let me know.
Some one was talking about somthing similar (I think ) a while ago on the physics forum which you might want to check out:

Hmm… a distributed virtual world that the creatures could evolve in would be really cool. I would be good to see how you get on with it.
hope the link helps if you havn’t seen it before.
