Sounds pretty neat. Sort of like Odyssey of the Mind[1] or Destination Imagination[2] for hackers. Although only one having one afternoon might make it somewhat tough. Or am I missing something? [1]: http://www.odysseyofthemind.com/learn_more.php [2]: http://www.idodi.org/index.php/the-organization
however, tilt is about getting experts and creatives from different fields to work together in a novel way, with no one person in charge. personally, i'd err away from anything that promotes the student/teacher relationship in this particular context.
i think an afternoon is sufficient for a themed competition - anything longer may be less accessible to a number of our participants. this could change in future events, but we'll have to see.
