I've been looking at that razar Naga, or even the WoW mouse, just to have all the extra buttons at my right hand.
Cool though that you found one that works on glass.
Gives me another idea.
I've been looking for a long time, for a simple, used bunk Bed frame.
The idea is to put my three PC's up above, and then use a cyclone fan to assist with cooling. Cables would easily drape down to the monitors, (which is slowly turning into a wall of monitors)
Now I have peg board being used under my desk top right now, for cable control, but If I got a good piece of sheet glass, I could easily fashion it in with the bunk bed frame, for the desktop, and remove the peg board.
