Open-Source.

I've decided that I'm going to embark on some sort of open-source project. This is a world that I have great respect for as a lot of really cool things have resulted from it.

The only problem is that I don't have a clue what I would want to do for it. I thought about trying to create a game engine of some sort, but I think that's a little ambitious. And there's already a lot of really great open source engines out there that I'd really only be copying.

So while I think about, I put it to the world. Or those that read this blog anyway. What sort of open-source project should I go for.
