Flutter has been included by Apple in its annual “Best Apps of the Year” section of the Mac App Store.  Flutter is described by its developers as “Kinect for Mac”.  You simply wave gestures at your Mac’s webcam to perform actions in other programs.  Flutter currently works with iTunes, Spotify, rdio, Quicktime, VLC, and Keynote.  Flutter was a part of YC’s Winter 2012 batch a year ago.  Flutter is a free download in the Mac AppStore.  Congratulations Flutter!
