'Eye flicker' explains optical illusion: Tiny eye movements may be responsible for the optical illusion of a famous artwork. The discovery hints at how we are fooled by other illusions too.
The painting, called 'Enigma', is a visual illusion created by artist Isia Leviant in 1981. It consists of concentric circles and radiating black and white lines. When looking at Enigma (see image), most people see what appears to be a flowing movement around the circles.
