Brought to you by the RFID & Physical Computing Hackers Camp, the challenge of identifying our suspect. We'll give you the hints, you give us the name. Prizes, perhaps. Fun, definitely.
How it's going to happen? We can only reveal this, watch a to-be-announced Jaiku channel for clues. And start improving your people finding skills. Flickr, Plazes, Last.fm, use it all.
Good luck.
(Gosh, is it obvious I just watched two episodes of a certain British series about MI-5?)
