Rear View Mirror is an application written in C# that connects to a camera device, either directly connected to your computer or a remote HTTP/MJPEG stream, and displays a window whenever motion is detected. It is intended to be a “Rear View Mirror” in my cubical so people can’t sneak up on me. It also has an MJPEG server built in so others can view your web camera.
** Update: Rear View Mirror now has its own website: RearViewMirror.cc**
