In the high street in the UK you would have found the type of shop you were after by looking out for a sign hanging out. There were signs for pharmacists, tobacconists, pawnbrokers, whatever. Nowadays there’s just one traditional sign still sometimes to be seen – the barber’s pole, as left in the animation. The barber’s sign shows a famous illusion. The cylinder is rotating horizontally, but the stripes look as if they are rising – which would be impossible, unless you had some long pole sliding through the cylinder. Geometric optical illusions. Optical Illusions - Introduction. Introduction What this web site is about This web site illustrates a new theory of visual illusions, which I developed.
The theory is of a computational nature. It predicts many of the well known geometric optical illusions, illusions of movement in line drawings, as well as illusions of three-dimensional shape. Arts: Crafts: Paper: Origami: Geometry and Modulars. Super Origami.
