This reminds me of https://www.youtube.com/watch?v=Jd3-eiid-Uw (2007) Johnny Lee's demonstration using head tracking with infrared led's and a wii remote to implement the same thing. Obviously that limits the effect to the individual's head being tracked, but its amazing its been 12 years since that demo and we're still trying to commercialize the same affect.

That was a great video, and highly hackerific. "That would be a bit goofy" is an expression you don't hear very often these days.
