One of the founders of Oblong Industries served as a consultant on the movie Minority Report, and the computing interface you see in that movie was developed based on work he did at MIT.  Now his company have made it a reality.  Really.  Check this video,

I’m sure that the data and the input method is strongly tied together but in a few years this is going to be truly amazing.  Of course, we’ve been seeing this kind of thing in fiction and movies for quite a while (Johnny Mnemonic springs to mind), but if we finally have real world applications then that’s quite exciting.

I would dearly love to have a go at one of these, although I’ve got no idea what I’d do (probably write a blog post, I guess not the most efficient method).
