Now, this might be achieved - David Copperfield style - by collaboration between stage hypnotist/illusionist and a complicit "subject". I happen to believe that Steve G Jones is the real thing. You will form your own opinion, on this example and no doubt on the whole phenomenon of induced illusions. (Many such example are to be seen on the Web. Are ALL faked?)
The most interesting aspects for me are the implications regarding human perception in general, and the nature of "reality". Anyway ... take a look. Can't see the wood for the trees?
