Brainchild?
How is it a brainchild? I seem to recall a certain BOFH article that involved electrical feeds through the keyboards - although ST has better ideas of using metal tracking on the keyboard keys themselves.
To be honest, though, this doesn't really seem like anything to 'wow' anyone. Two idiots with no self control showed how they like to punish themselves...if I want to watch that there are plenty of adult sites I could visit - and those guys know how to do it properly.
