PixelPeeper allows you to watch a pixel on your screen.

PixelPeeper allows you to watch a pixel on your screen and execute an AppleScript when that is pixel changed. This can be used to alert you when a long operation is complete. For example, you can watch a pixel within the progress bar/window when performing a software update or installation, downloading or copying large files, or backing up your system.
