Photos: Hacking at Defcon

The Electronic Frontier Foundation organized a decidedly nondigital fundraiser at the Defcon convention: a dunk tank.

Isaac Levy, a member of the New York City BSD User Group (pictured in the dunk tank) said he volunteered for the job "totally to support the EFF." By late Saturday afternoon, after nearly two full days, the foundation had raised about $2,000.
