It is really quite amazing how your brain interprets the information that the eyes send to it. If an illustration is done in a certain way that suggests things that are not there, the brain fills in the gaps and actually thinks that it sees the suggested elements. This post has some interesting illusions where the brain shows us the things that are not there at all but it sure does look like they are.
Your brain will tell you that these circles are moving, but they are not – really!

The two vertical lines are both straight, but they look as if they are bowing outwards. The distortion is produced by the lined pattern on the background, that simulates a perspective design, and creates a false impression of depth.
In the accompanying figure a white equilateral triangle is perceived, but in fact none is drawn. This effect is known as a subjective or illusory contour. Also, the nonexistent white triangle appears to be brighter than the surrounding area, but in fact it has the same brightness as the background.
The term illusory motion, also known as motion illusion, is used to define the appearance of movement in a static image. This is an optical illusion in which a static image appears to be moving due to the cognitive effects of interacting color contrasts and shape position.
This is the famous Penrose Triangle, also known as the Impossible Triangle. Though it is something that most of us have seen before, it is always cool to see how easily our brains are fooled, even when we know that it is an illusion.
The Blivet, another well known optical illusion, still gets most people every time, regardless of whether or not you know what you are looking at and try not to see it. Another illustration of how powerful the brain’s interpretation isn of what our eyes take in.
