We've all had our days when we've been extremely bored and can't think of anything to do. Well I had one of those days last weekend when I was with my friend Joe. We couldn't think of anything to do. There were some ideas, but everything just sounded boring. After a while we thought of an idea of looking at optical illusions to kill some time. We went online and found a great optical illusion website. Some of them are just so crazy. They are all very entertaining. There is now a cure for boredome.
About Optical Illusions: An optical illusion (also called a visual illusion) is characterized by visually perceived images that differ from objective reality. The information gathered by the eye is processed in the brain to give a percept that does not tally with a physical measurement of the stimulus source. There are three main types: literal optical illusions that create images that are different from the objects that make them, physiological ones that are the effects on the eyes and brain of excessive stimulation of a specific type (brightness, tilt, color, movement), and cognitive illusions where the eye and brain make unconscious inferences.
Here is the great website we visited(VERY entertaining!): http://www.123opticalillusions.com/
