Flutter Flutter

This isn’t the first Mac app to offer audio playback control via hand gestures, but none has worked as well as Flutter (Free), developed by the company of the same name. Described as “Kinect for Mac,” the app only recognizes three gestures, but they let you play your music, pause it, and skip back and forth between tracks using just your Mac’s FaceTime camera and your hand.

Flutter works with iTunes, Spotify, MPlayerX, and Quicktime. To start or stop a song you simply hold up your hand from one to six feet away, with your palm towards the screen. Make a fist and point your thumb left to move back a song or right to skip ahead. The company promises support for more apps and gestures in coming updates, but this is a nice start for a free app, and fun to play with.
