From David Morrissey
Gentlemen! Battlestations!
"Thin piece of board duct-taped to the arm of the chair (with piece of old shirt as base, so no glue gets on the chair) puts the mouse immediately under your hand; the leather glued to the top of the board provides a smooth but low-slip surface for the mouse; and the packing styrofoam from the end of the PC tower (reinforced with duct tape, of course), sits on your lap to put the wireless keyboard at your fingertips."
Your move, carpal tunnel syndrome.
