If you have generally poor circulation or just find that your hand gets mighty cold when using the mouse for an extended period of time, the USB Warming Mouse Pad is one of the most useful useless gadgets around. To be brief, this fishy keeps your hand warm.

If your house is drafty, especially during the winter, you may notice your hands getting cold when on the computer. With your arm slightly elevated, the blood tends to run out of it, leaving it frigid. But with this hand warmer, you can keep toasty and get work done.

You plug the fish into a USB port, run the mouse cord through the fish and out the back and then put your hand inside the mouth. It heats up slowly to about 107.6 degrees. That sounds pretty warm to me, but I guess if your hand is really cold, this would be a godsend. You can your own aquatic hand warmer for $22.
