Made my cheap webcam perform much better.

This software installs a menu in the upper right of the menu bar, allowing you to control your webcam’s hardware directly. For my Logitech camera from 2004, it allowed me to control all the picture settings (brightness, contrast, exposure, focus, color temperature, saturation, etc.). Now my useless webcam has new life. Dunno why the haters are hating, because it works fine for me, even on Yosemite.
