Scintillating grid illusion. This illusion,based on the Hermann grid,was created in 1994. When the grid is observed,the white dots at the intersection of the grey lines appear to scintillate - flickering between black and white. If a single white dot is stared at for a while the effect disappears. It is thought to be caused by the processing that takes place in the eye and the brain to produce the final image that we perceive | |
