http://blog.audiovideointeriors.com/208great/ Wow! I could've bought something better for $6,000,000. Sheesh!
It is cool, but I think i'd rather just have a standard surround sound system (or a decent one) but have stadium type seating so that it could fit more people for superbowl parties and such. A single couch just isn't enough, it should have recliners instead.
Definately needs more seating. As far as selling it to people like Lucas, Spielberg or Jackson my guess would be those guys have home theater systems that put this to shame. I wouldn't doubt if movie big shots like those guys get stuff that isn't even available yet donated to them.
