    I've always wanted to create my own Java based forums software but that might be a bit of a big project. I'm keen on doing a small game using OpenGL with you if you like. Just as minor as minor can get really, start small.

    It's not much yet, but here's what i've got so far:

    Default Re: Need a project

    I was wondering if someone would develop the graphics/gui? Right now, I pretty much have place-holder objects. Sound/Music would be nice, too.
