The Poppenkast is going to have a 4-hour development jam this Sunday. The rules are pretty lax. Just make a game. We'll be hanging out on the #poppenkast irc channel on irc.slashnet.org during the jam.
You don't have to spend the whole 4 hours on a game. If you're short on time, stop by and just make something quickly. It's going to be a monthly thing, happening on the second Sunday of each month.
