Logisys Optical Finger Mouse
Strap this optical mouse made by Logisys onto your index finger and use the 800 dpi laser on any media (except reflective glass surfaces) to easily control the cursor. The desk, keyboard, wall, even your own clothes will work as a functioning surface. Even more convenient, the scroll wheel and left and right buttons are easily usable with your thumb to scroll and click through your applications. The next step is losing the USB cable it uses to connect and going wireless.
