Here's a USB powered desktop sniper, for sniping those annoying colleagues from far away. This tiny gun fires plastic BBs. I love it, therefore I must have it.

The sniper is powered and aimed via a USB connection to your computer. It comes with a small camera above the barrel to let you see your targets on screen. But at $100 I'm not so sure I'll love it just as much now. Great idea though. [Donya via Craziest Gadgets]
