gorilla arms are a thing you cannot dream your way out of. While a display projected 'in air' is cool a standing gesture based ui is very much not.

What if we think those displays as VR headset alternative? I feel it could be hugely helpful doing surgeries/repairs don't you think? Direct brain connection means too many cmd-z's for me.
