I too was fascinated by those Magic Eye pictures. Although my first reaction was quite the opposite. In fact I was downright sceptical, and believed this was another marketing scam. Especially since I stared for minutes on end at the first picture, unable to make anything come to life.
But after a little coaching by the shop owner, I stared at infinity, and slowly the image emerged. Now, I cannot resist them.
I guess this scepticism is the natural reaction of all thinking people to something new.
