Optical Illusions

My favorite optical illusion is the one where the line look crooked but when you put your mouse on it the back ground goes away and the lines that make up the square are actually straight.

here is how it is supposed to look http://www.michaelbach.de/ot/ang_hering/index.html it's the second one

When you look at it with the background the box in the middle seems jagged but that is because on the background the gray boxes just makes the lines on the red square off but they are perfectly straight.


I like this one too because I think it looks interesting. I like the black and white colors they picked because I think it works better than with any other colors. This optical Illusion is asking if the center circles are the same size. They are. You may think the one on the left is bigger but that is because its surrounded with smaller dots. Which makes the center dot look bigger and vice versa for the one on the right.
