This great site was very informative for me. I though optical illusions or toys were new things that came into our stores not too long ago but I guess I was proven wrong. Optical illusions have been around for many years and some are quite historic. My favourite one would have to be the Chromatrope or better known as the kaleidoscope. Back when it was first invented it was large glass disks turned by a large handle in front of a "magic lantern". This gave a trippy surreal look when you looked through it. Later on the more convenient kaleidoscope was made and became pocket friendly. I never thought before looking at this sight that optical illusions were so complex or have been around for so long but the only way for you to find out is to look for yourself. CLICK HERE
