I was just waiting for the chair to break off and go flying across the room... Now THAT would have been a fun ride!
I've seen a similar thing to this before in development; essentially, it was one of those fitted with several seats (6 i think it was, 3 in front, 3 in back all facing the same way) and the whole assembly was setup on a rail system. Looked interesting. I'd rather just hop on a rollercoaster, though.... goes faster. :P
