This has got to be the coolest (albeit most useless) USB gadget around, the USB powered Snowbot.
The Snowbot looks and sounds like it has come off a set of BattleStar Galactica (thank you ScFi). Simply plug it into any free USB port and watch the Snowbot’s LED robotic eye scan from left to right.
For added fun you can adjust the speed of the eye scan, switch the spooky robotic sound on and off and even manually move its articulated arms (what more could you want from a robotic snowman).
The Snowbot is available from ThinkGeek for $14.99.
