not sure if serious, but...
Check out:
Logitech iFeel mouse
and for the truly nostalgic gamer:
BELKIN Nostromo n30. I had one of these back in 97 and it was cool as hell. The 'immersion' software was crazy when you could get it to work. Playing q2 with it was a blast.
those 3d mice?? you hold it like a pencil or something and it pushes and pulls you? does not look like a precision tool, but looks like the feeling of moving about in a fps could be quite interesting(holding the butt of ur weapon like a pencil though)
