Gesture control is all the rage these days. After all, there’s something inherently cool about being able to control your computer with a wave of your hand. It’s the sort of thing once reserved for the realm of science fiction, right up there with holographic user interfaces.

While the latter is still a bit out of reach for the average user, the former is getting a lot more common, particularly with the release of peripherals such as Microsoft’s Kinect system.

But what if you don’t have the money to shell out for a Kinect(or simply can’t be bothered to purchase one)?

Ladies and Gentlemen, meet Flutter.

It’s simple (albeit brilliant) premise: the application connect’s with your system’s webcam, and allows you to use gesture controls to change, select, pause, and play music and videos once you’ve selected a ‘preferred’ app (basically, that’ll be the application Flutter controls by default). As an added bonus, the application is compatible with YouTube, Netflix, Pandora, and Grooveshark, in addition to supporting most media players (VLC, Windows Media Player, iTunes, and QuickTime are a few examples). An excellent idea, to be sure – and a great way to put your webcam to use when you’re not actually utilizing it for video chat.

When you aren’t using Flutter, it’s a simple enough matter to turn it off: all you need to do is toggle it with an icon in the system tray.

Flutter comes in a few flavors: those of you with Windows 7 can download the msi from the app’s official website, while those of you who plan to install and use it in Chrome can nab the app on the Chrome Web Store. It’s also available on the Apple iTunes store, as well.
