[Nuri] sent in his rather interesting gaming feedback device. The TrakonyaMutatorUSB is a USB based armband that’s designed to shock you when you get shot or killed in your game. I can’t comment on the safety of this thing, but I guess it could be a good gift for your enemy gamer.
Update: Just to clarify a bit, This is built by [Nuri]. He offers them for sale (via paypal I see), but it is his work. It would be nice to see the design, but I can see some reasons why he might not want to release it to the public.
