How much control are you wanting to exert over creativity? As in, are you waiting for someone to come up with something that "just clicks", like 2 of my last jobs were (that I didn't even get to finish as a result and wasted much of my time and energy), or are you more willing to let the artist art?
I'm interested in contributing, but I'd need to gauge that first. Additionally, I don't have the software I would need to do anything hardcore right now, but I have some stuff you can look at so you can gauge if I would fit into your project.
