Holographic screen


Recommended Posts

From wikipedia: "Holography (from the Greek, ????-holos whole + ?????-graphe writing) is the science of producing holograms, an advanced form of photography that allows an image to be recorded in three dimensions. The technique of holography can also be used to optically store and retrieve information. Holograms are common in science-fiction, most notably Star Trek, Star Wars, and Red Dwarf."

So that would be a projector pointing at a table that changes shape?

I remember watching something on tv where they used mist as the backdrop to project the image onto, they said it could be used for advertisment, so say your walking down a street you could see an image on the side walk and just walk right through it.


Just on a side note i came across this http://www.youtube.com/watch?v=zEax1mJhJQ0...ted&search= and thought it would be pretty cool to play a game like that.
