Presidents' Day Optical Illusion

In honor of Presidents’ Day here in the United States, today’s illusion features Barack Obama, the 44th U.S. President.  Both photographs of Obama look fairly normal when viewed upside down.  When the images are inverted, however, it is obvious that his eyes and mouth are upside down on one of photographs and normal on the […]

This animation of an impossible ribbon was created by Erwin Bonsma.  Depending on how you look at it, this ribbon can be perceived as rotating in two different ways.  He credits the original idea to M.C.

Relative Size Animated Optical Illusion

Perspective matters.  The angled lines in the animation presented below give the impression that the floor is sloping downward to the left.  As such, the man standing on the left appears to be much shorter than the man standing on the right.  As the man on the left walks up the incline to stand directly […]
