Ok this is one of those "I day dreamed about building something like this but it was impractical" things. A friend of mine built a computer chair out of a BMW seat [1] and we talked about what you could do if you were to machine your own parts. I definitely like the idea of the screens pulling up and away and letting you step out.

Ergonomically I wonder what it would be like to be able to type in a recliner. I do that with my macbook on my lap or a lap desk but my hands are always in a somewhat weird position to do so.

And of course you need to mount a Leap Motion controller on the arm looking "down" so that you can just point at a window to move it around.
