Want to really drive a coworker insane? Stash this ThinkGeek Annoy-a-tron 2.0 ($12) somewhere in their cubicle. This noisemaker is so tiny, it'll most likely take them weeks to find it. In the meantime, you'll be able to torture them with a choice of six obnoxious tracks, from cricket chirping to our personal favorite, "Grating Electronic Noise".
