VUWER (Vanderbilt University Web Enabled Recovery) is a free, open source, Mac OS X background app that assists in the tracking of stolen Macs. The app checks a web or remote computer account at regular intervals, in the background without disrupting use. If a computer is stolen, the owner can change the message that VUWER reads in order to track vital information.

VUWER can collect screen capture images of what the thief is viewing. It can also activate the iSight camera to capture images of who is in front of the Mac and capture geolocated IP address information. This information is forwarded to the owner silently, in the background, without the thief catching on.

Additionally, VUWER is written in Applescript, so it is simple to modify.
