I'd like to participate in
http://globalgamejam.org/ this weekend.
It should be interesting, I'll probably work with a friend of mine who knows more about Java. He's a good programmer and I offered to make artwork and help with design and, well, making it fun. But 48 hours... I've never done anything like it. No idea how it's gonna work out. Also need to make sure I can get to the local meeting place at the start of the thing.
And hey, maybe if I like this I'll enter a Ludum Dare contest on my own, just starting with the more "relaxed" variation. (72 hours, more lax on using pre-made resources)
