We have seen the future of computer mice, and it just might be the Axsotic 3D-Spheric-Mouse, which "lets you control a three-dimensional object by just grabbing onto it and moving it around." No word yet on pricing or availability. Video after the break.
The mouse itself is stationary, but that round ball in the middle is effectively free-floating. You can pull it, push it or twist it and a system of sensitive springs and magnets will translate those motions into movements in a 3D environment as panning, zooming or rotating, respectively.[via Dvice]
