Mice have traditionally been two-dimensional creatures, offering an easy way to navigate around flat and boring desktops. Now that 3D is a new buzzword and everybody (and their parents) are cruising around Google Earth, it's time to take advantage of all those extra degrees of freedom.
The Axsotic 3D-Spheric-Mouse lets you control a three-dimensional object by just grabbing onto it and moving it around. 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 — with a precision of over 2,000 DPI.
