What is badger?

badger is an iPhone app designed to annoy the spit out of your friends and family. Once activated, it will play a random tone (2500 kHz, 5000 kHz or 7500 kHz) at a random interval between 1 and 10 minutes. The beeping will be frequent enough to drive people crazy, but infrequent enough to prevent people from tracking down the source.

This has been a huge hit at work, if you can call it that. And once they found out what was causing it, they all wanted a copy.
