As a film major and a huger lover of the sci-fi genre, it makes my day when movies and real life coincide. Elon Musk (co-founder of paypal and chairman of Tesla Motors) has created his own, real life, version of the Iron Man labs where people are able to interface with computers using only gestures. The video below shows his technology being used to build and manipulate a rocket engine. His lab has even moved so far as to use goggles that create a virtual world where you can actually move around the object and work with it. And although I'm sure it's quite expensive, the technology the lab uses is open for anyone to buy. Read about it here.
