Microsoft’s wildly well-known Kinect controller for the Xbox 360 brought motion-based controls to the masses when it launched in late 2010. While equivalent technology will be built into a variety of consumer electronics moving forward — particularly HDTVs — Mac customers now have access to a totally free app that will add gesture controls to their existing OS X computers. Presently compatible with just two applications, iTunes and Spotify, the Flutter app for Mac allows customers to manage music and video playback by producing hand gestures that are recorded and relayed by the PC’s built-in iSight camera. The app is an early alpha create, but we discovered that it performs as described and it worked nicely even from a few feet away. Flutter is not however obtainable in the Mac App Retailer, but it can be downloaded for free of charge directly from Bot Square’s site. A video showcasing the app follows below.
