Kinect-Like Gesture System for iPad to Be Demoed at CES (includes video). The product is Mimesign from Elipticllabs:
When interacting with a toy or a gadget, the user shouldn’t have to change her state of mind. Rather than entering a mindset where high precision is required to locate the right button or icon, Mimesign seeks to create a different and more natural bond between the user and the device.
In the future we will interact with all our devices by doing tiny techno dancing at them.
