Bjorn Borg Hollow FaceCategory: 3D Illusions | Added: August 29, 2009 |
6 commentsThis picture of Bjorn Borg created and used in experiments at Uppsala University in Sweden appears to be convex in that it is raised outwards from the frame towards you. In reality the image is actually concave, it is pushed inwards away from you. This type of illusion is known as the 'hollow-face illusion'.

Fraser Spiral IllusionCategory: Shape and Color | Added: August 29, 2009 |
4 commentsDeveloped by psychologist James Fraser in 1908, the Fraser Illusion appears to be a spiral pattern converging in the distant center with a black, white and grey chequered background. In reality the spirals are not really spirals at all but a series of concentric circles, the background gives the illusion that the circles are spiralled.
