How do you create the world's largest mouse? Here's how. Designer Weston Boege's Glide Keyboard is both a mouse and keyboard. Resting on low-friction pads, you simply slide the keyboard around your desk, just like an optical rodent. If that little workout is a bit too much, Boege has thankfully included traditional mousing controls right in the molded palm rest.

Of course, given the limited desktop estate we have in our mousehole of a cubicle, this idea may look mighty cool, but may just not be so cool to use.
