The concert was held in a store that sells sound systems, TVs and the like. They had a sample 3D home theater with $200,000 worth of equipment in a sound-proof room that also cost $200,000. For a sample, they showed scenes from "Avatar" and the motion of the chair made me almost as queasy as the movie.
I just didn't see the need for it, which is good because I could not afford a downpayment on such stuff.
