Is a holographic PC possible?

[Xclusiveitalian]

I was watching the movie "(2002)The First $20 Million Is Always the Hardest" and in the movie they design a holographic computer with no keyboard, or mouse that is fully interactive. I was wondering if it is possible? Of course it's just a movie, and they made it look so easy but I was just wondering.

If you want to spend the money... But search for possibilities... as if anything fun is being done, somebody has already tried it.
