Apparently Japan has invented a computer controlled holographic display? Isn't this the holy grail of 3D display technology? We can finally have 3D TV's without the glasses once this technology becomes widespread. Does anyone know how they did this?

You know how you can drag your route around when you get driving directions on Google maps. I think it would be a neat idea if they tracked how users changed their routes, and then used that to improve their directions. People change routes to account for traffic, times of day, stop lights, closed roads, etc and Googles algorithm probably doesn't know about those things right now when generating directions. It really would revolutionize directions.

What say you, Slashdot?
