What's the theme? I don't understand the page.
The theme is revealed and BAM! 48 hours to make a game. The theme reveal is when the clock starts ticking.
It's currently at around 10 hours 40 minutes, which makes me feel some pain for Notch since I'm in his timezone (Stockholm, Sweden).
It's 16:18 in the afternoon here now, so the reveal is at 03:00 in the night. Not my peak hour for programming. :)
Its a neat way to think about game themes; a useful list to have.
