I was on the team that won the shredder challenge. I talked to one of the UCSD people afterwards and he practically convinced me that my team did it. After a while I realized that it was so damn easy to sabotage their effort that I didn't really care if my team did it because that's what happens when you invite the whole internet to your party. Now I guess they managed to clear us of that. :) Unfortunately, when this Adam guy wrecked their program, he wrote them a letter which simultaneously implied that he was our team and the group "Anonymous" at the same time. Some people at DARPA seemed to believe that claim (even though I used my real name to sign up) and so DARPA was very hesitant to announce that we had won the competition. It was a fun competition though.
