Congrats on another successful project! You have some great stuff and I love playing around and experimenting. If you don't mind me asking, what language(s) and tools are you using for your evolutionary simulators? I've been trying to do something in this area using Codea on the iPad (it implements Lua in a Processing paradigm). I don't think it's the ideal way to go (though I LOVE Lua); since you are creating the sorts of things I like most, thought I would ask!
Thanks for all your hard work and awesome software.
