Flutter is a small app that uses your webcam to let you pause or start your music playback with a hand gesture. Simply install Flutter, open your music player and listen to some music - to pause playback, just hold up the palm of your hand toward your webcam for a second and the music will stop.To continue listening, simply us the same gesture again, and Flutter will resume playback. A similar gesture is supported for skipping to the next or previous track.Flutter works best if you gesture within a 1-6 feet distance from your webcam. If you get too close or are too far away it may have difficulties recognizing the gesture. Flutter runs in the system tray and will automatically activate your webcam when you launch your media player.Currently supports Windows Media Player, iTunes, Spotify and WinAmp.
