Richard Brooksby of Otterly hosted two game jams, one lasting 3 hours and another lasting a whole 24 hours. At game jams, people get together and make video games in a limited time, with a surprise theme. Attendees were challenged to make complete, playable games, working individually, or in small groups, starting from scratch. The results can be found over at CambridgeIndies with entries for Strawberry Jam and Blackcurrant Jam.
