Imagine you could flip through Web pages, play videos or scroll down important documents with a simple hand gesture.\u00a0A free download called Flutter for both Apple and Windows gives a glimpse of how gesture technology could improve productivity. For now, Flutter allows you to use gestures to control your video on YouTube and Netflix and music on Spotify, iTunes, Grooveshark and Pandora. The app uses the built in webcam on your desktop to read simple hand gestures for starting or stopping music or video. Here's a brief demonstration: Google Acquires Flutter Flutter announced being acquired by Google last week. TechCrunch estimates the deal could be worth around $40 million. Writing about the acquisition on the official Flutter website, CEO Navneet Dalal explains: "Today, we are thrilled to announce that we will be continuing our research at Google. We share Google\u2019s passion for 10x thinking, and we\u2019re excited to add their rocket fuel to our journey." It is uncertain yet whether the Flutter team will go on developing and upgrading the company's existing product or bake their technology in to Google products like Google Glass, for example. Flutter is hardly the only company developing products using gesture technology. Other examples include PrimeSense, Leap Motion and Omek Interactive (recently acquired by Intel.) But the acquisition is proof again that development of a single useful and revolutionary tool can catapult a small startup to a huge payoff.
