LookAtMe is a software that uses video input to analyze movement. It has little eyes that sit on the menu bar and follow your movements, reacting to bright light or darkness. This version has fixed bugs that caused the preferences window to get lost and the pupil style not to be saved in user defaults, as well as improved cat-style pupils, motion tracking using RGB instead of grayscale, iris, colors that accept alpha values, and softening shadows.
Launchd(8) frontend for Mac that allows you to manage and debug system & user services with a sophisticated interface.
