Hehe, I'm amused.
Not just by the topic, but the people exaggeratingly ticked that it's being made first for work related purposes. Like jumping straight to interactive shoot'em up would be better.
I can picture these becoming the cubicles of the future, much like the cubical was supposed to be the office of the future, except this time with a potentially more positive outcome.
From the outside, rows and rows of black spheres like a nest from some alien movie. Yet, inside each one is a worker, a desk, a chair, and let's say a beach resort.
Seriously, it could help relieve stress at the workplace. Add in motion and touch controls to everything as well as cameras to display a co-worker's office so if you ever want to chat with a friend, get some feedback, or have a virtual nerf war you never really have to leave the workstation.
I'd love to see a house made out of these, honestly. That'd be the coolest house ever. And by these I mean HoloRooms, not the spheres, that'd look kinda silly.
