"Princess Leia"-style holograms

I didn't realise how far holograms had come. Business 2.0 describes how Ford used holograms to create a prototype car that viewers could walk around. As the article and the Slashot thread say, the easiest way to imagine it is to think of the Princess Leia hologram in Star Wars rather than those glass "2D" holograms that used to be all the rage. Zebra Imaging is the company responsible for the technology and it sounds impressive (or use the Google cached version as their site is down right now).
