If no one objects I’d like to contribute my meager artistic skills. I’m all booked up in the coding department at the moment.
I’m working on an interpreted language with green threads and what not, for AI. It has a proper expression parser that converts to stackbased ‘bytecode’. With this, many ‘entities’ can run their (potentially multithreaded) code on the same thread.
I hope to post a demo in a few days. I think this project can take advantage of it (same for the RTS project), but I consider it a separate project.
Anyway, this Sandbox projects needs some design and codebase!
I’d be able to help out but I can’t helm this, as what appears to have been expected of me. So if somebody else starts everything off and organizes everything, I’ll be able to do some work on the side for it. Right now though I’m just really tired of game coding, seeing as it’s my actual job and I already do it 40+ hours a week. I’ll regain hobby interest again, but for now I just want to sit around and watch movies and read books in my very short free time. 
Monkey man ! 1st off I founds you !
Anyways being the worthless loser I’m I have tons of free time, and no exp with Java… >.> BUT I’ll make ya some arts if ya need any…
Hahahahaha.
Good to hear from you, man. It’s always nice to be someone who needs finding.
I’m sure this project will need lots of artists, so if you’re interested and someone actually organizes this thing, then sweet.
