Update: the annoyatron 3.0 is not available anymore, but you can get the awesome AnnoyingPCB here.

Back when I was working in an office, I used Thinkgeek’s original Annoy-a-tron quite a lot to annoy a speial someone, but that was a long, long time ago. Now, the company has just released some new and improved editions of the original gadget!

The Annoy-a-tron Prankster Pack contains:

-Annoy-a-tron: Periodic beeps and sounds make your friends crazy hunting for that ANNOYING NOISE.
-Ringtone Annoy-a-tron: RINGING AND BUZZING will drive friends bonkers looking for the missing phone!
-Eviltron: Unsettling spooky sound effects SCARE THE CRAP out of your friends.
