The Zen of killing
This is what I would call a challenge. Try to kill your best bud in a Quake 3 Arena deathmatch without breaking a sweat. France Cadet, the French artist who works with gadgets, has made a three-person Arena rig with a Sweet Pad. The Sweet Pad is a USB controller that requires a gentle touch to use. If you get too twitchy you'll lose control, and probably lose the match to a cooler hand. I'm not sure this would be fun for more than a few minutes, but it's intriguing. We all hit that groove once in awhile during a deathmatch; but what if you had to be in that groove from the moment you sat down at the monitor?
Talk about performance anxiety.
