If the ceiling represents his/her sky, what's that on the wall, the window?

On another note, that must be an interesting room to live in.

That's a stupidly positioned projector there.

It could be like a window, though the image shown might need to be adjusted. Wouldn't that be cool feeling like you're living in the sky?

What if they put a wireless chip in the headphones (or something, no implants plz) that sent x,y,z(etc) position in the room to adjust the images on the projectors. So when you go over to look out your "window," it would be more realistic. Then you can look down, and see the earth far below you.

(Of course that won't work for anybody else in the room, but this person is clearly very lonely~)

Now you're thinking with portals.
