"Seeing" is an action is done commonly by the human eye and brain, where both of them are responsible for interpreting observations, such as estimation of the shapes, size and color of the objects, as well as the motion detection by analyzing the data is sent from the eye to the brain. There are some cases of "seeing" in which the brain perception is different from what exists in reality in other words, an error in the process of "seeing" is happen. In the nature, such experiences usually are not seen, but certain patterns can be drawn in which animated interpretation from static shapes may be produced by the brain. This type of motions is named "illusory motions". In the last two decades, a special attention allocated to the illusory motions. In this work, we are providing new patterns having illusory motions. As well as, we present some ways to maximize this type of unrealistic perception and try to interpret this kind of unrealistic seeing.
