FPS Circle of Death
"A circle of all the important FPS keys surrounds your left hand in a unique configuration. Arranging your fighting space, and centering your FPS energy. The keys are made to be silent, adding a little verisimilitude to any stealth gaming operation. In addition to the 40 specialized keys for FPS gaming, handy volume controls and 12 function keys ensure everything needed for maximum in-game efficiency is at your fingertips."
Egad... our heads hurt just looking at this thing, to say nothing of the carpel tunnel syndrome just twitching to come out of retirement after a few hours of gaming with it. Though it's an interesting design, it definitely can't hold a candle to BigWops clicky-clacky IBM mainframe-style keyboard. If you're game, you can pick one of these discs of death up for a modest $30 - $40 with Counter Strike: Source.
