PyWeek 12 is a game challenge/competition. It goes for a week. It starts on 2011-04-03.
It's kind of open source: code needs to be visible, FSF license list is recommended, open source license appears not to be required though. See rules for rules.
Here's the initiator's blog (+feed) - in case you're the stalker type. I know I am. :)
Horst, a Wien-based friend of FOSS hosts the Python Game Book wiki and Spielend Programmieren ("Programming by Playing") which is a wiki used for his courses teaching kids to make games using open source tools and libraries. There might be a guest post by him on this blog sooner or later.
Some cool kids on his YT channel.. I hope you like das German.
