I saw a similar mirror in a novelty store in burlington vermont,i think it was the discovery store there.It was a simple mirror ,bowl shaped and if you sat like a coin or something small in it apeared to be bigger and 3D.A stange trick on the eyes.thats why i want one of these machines,very one of a kind.i think they could have done much more with this machine.The game time traveler and holloseum were so so games but the technology was a head of its time, no speacial glasses needed.That why i want one so bad. I WOULD PAY UP TO 3000.00 FOR A WORKING ONE IN GOOD SHAPE MAYBE MORE.
