If you have a Wii Remote and bluetooth on your computer, you can use this handy script I whipped up in glovepie.
I won't go into detail, google glovepie and use this script.
Key.Up = Wiimote.Up
Key.Right = Wiimote.Right
Key.Left = Wiimote.Left
Key.Down = Wiimote.Down
Key.PageUp = Wiimote.B
Key.PageDown = Wiimote.A
Arrows for up down right etc, remote is held with arrows at top, B to change hands, A to toggle things like a welder.
Recommended usage: Mouse in right/left hand, wiimote in other, run around and stuff!
