The Heliodisplay projects TV, streaming video and computer images into free space. It is also interactive — a “floating touch screen” — allowing a hand or finger to navigate and select objects.

Pretty stunning in my mind, even just as a technology demonstration, and you can even buy early models. Just imagine the future applications, especially as the price drops from the current $19000USD for a 15″ model.
