A bit pricey at $10k but very cool immersive app that allows the surface to use a camera to then control all of the various gadgets in the room. Might be a fairly cool app to try to duplicate as part of the course.
The approach, Cristal, uses gestures to control the various devices and I am assuming, a fair amount of under the hood operation to get things going. It would be very cool if you could blend a limited range Bluetooth to automatically discover devices but the camera input is a bit more intuitive, i.e. I see what is in my room and then can manipulate it.
