Rising Object Illusion

Best Illusion of the Year Contest - 2021 Kokichi Sugihara “Rising Object Illusion“ Institution: MIMS, Meiji University Country: Japan Author description: A lying object rises when it is reflected in a vertical mirror behind it. The object is typically a columnar body and the axis is horizontal directing toward the viewer. However, in the mirror the object rises with the axis directing vertically. The truth is that the object is a horizontally placed picture expanded by (i.e., the square root of 2) in the direction of the axis, and this visual effect occurs when we see it in 45 degrees downward.
