I went to the App store and found this app called "Flutter". It's free and what it does is revolutionary. It will change the way we think of as computing - forever. All you have to do is raise your hand up to the camera and it recognizes that gesture. When it recognizes your hand, it will pause/play the song on iTunes. http://www.youtube.com/watch?v=nQnvmb9KiRA If Apple made this technology deeply integrated with OS X along with Siri, we might not need a keyboard and a mouse anymore. I know some iPhone 4S owners who never use Siri. I am not one of them. It takes some mental adjustment to grow accustomed to issuing vocal commands to your phone. But now that I’ve mastered the habit, it’s both instinctual and quicker to tell my phone to schedule a reminder, set a timer, or send an iMessage than to make it happen with my fingers. I imagine getting accustomed to using Siri on the Mac would take some time, too. I’m willing to put in the effort, though, because I already see how much time it saves on my iPhone, and how much joy the service brings. All I need now is for Apple to add the functionality in Mountain Lion. What do you think?
