Pranav Mistry demonstrates the real-world application of his SixthSense technology which enables people to seamlessly interact with ordinary objects and digital objects using natural gestures. For example, your hand becomes as phone or a sheet of paper a laptop. Watch the video, you will be slackjawed by the time you reach 6:25.
As Mistry states at the end of the video, he plans to make available the software behind SixthSense open-source. Forget Derek Jeter or Lady Gaga, these are the people our kids should aspire to be like.
