Early in 2005, my iBook was stolen right off my desk, probably in broad daylight. Total nightmare. Never got it back. So I was thrilled when Keith Hall (aka Mac programmer genius) showed me Undercover: a unique theft-recovery application designed from the ground up for Mac OS X.
It’s basically spyware that you launch on your own Mac if it get pinched. Sends you screenshots of the thief’s activities, triangulates their IP address for physical location, and even takes photos of the thief if you have an iSight.
Fan-frickin-tastic.
