Control your music like a ninja with Flutter

You’re jamming out to your favorite track on Spotify, and then all of a sudden a song that makes your want to scream starts playing. Instead of running over to your computer and frantically pressing keys and clicking at your screen to make the madness end, Flutter lets you wave at your webcam to change the track.

With Flutter, you can use a wave or hold up your hand to control iTunes or Spotify music on your computer. All you need is a webcam and the app. The company boasts that more than 50,000 gestures have been used thus far with the app.

The technology is similar to Microsoft’s Kinect, but Flutter points out that Kinect is limited by the hardware and the fact that it can only be used on the Xbox and some Windows programs. “Flutter is Kinect without the hardware,” said co-founder Mehual Nariyawala during his presentation at Y Combinator’s Demo Day. “Naveet, my co-founder is the Tom Brady of computer vision,” said Nariyawala.

Flutter has gained so much attention that Daniel Ek, chief executive of Spotify, even tweeted about the company.

Flutter is one of 39 companies presenting at Y Combinator’s Demo Day Spring 2012 event. Check out other cool companies making their debut here.
