follow or trace the spiral and you will find this is not a spiral at all, but actually a series of concentric circles. This illusion was created by British psychologist James Fraser around the turn of the 20th century, and is known as the Fraser Spiral. it appears a single line is twisting its way into the center, spiraling into a funnel, but your eyes are deceiving you. The Fraser Spiral works by guiding the eye through a sequence of counter-angles. The eye and brain are not accustomed to processing images this geometrically complicated, and thus try to normalize the circles by imagining them as a single line, a phantom spiral corkscrewing its way to the center. The Fraser Spiral artistically falls somewhere between Rene Magritte’s painting, This Is Not A Pipe, and Nothings Moving
