Touchable Holograms

Popular Science posted this article and video about touchable holograms at Siggraph '09, this year. It's a combination of three items: a 3d display using concave mirrors something like this 3D mirascope toy, two wii-motes strapped statically for position detection, and a home-brewed (university-brewed?) phased array of ultrasound drivers.
