if I saw this implemented in Blender, I'd have a shock! (future shock that is

basically, it'a "mouse" with six axes of movement, plus five buttons(you know, the fingers!)
I suggest checking the demo section, the second movie. You actually see a scene where a guy uses the glove to work in a 3D creation proggie(don't ask me what that was).
wouldn't it be cool to move vertices by grabbing them between two fingers and moving your hand in 3D?
God, if I'd see that in Blender, ...geez...
by the way, there IS a SDK on that page, which means that it CAN be implemented in Blender...somehow...
