This optical illusion should squirm under your gaze.
Friday I was looking for 3D optical illusions for an art class. I found a web full of wonderful 2D illusions in the process. The ones that intrigued me the most were those that appear in motion because of the automatic responses of the brain.
To know theoretically that the brain is constantly making calculations unnoticed in the background to process the input of my eyes is one thing, but to see its actual attempts to adjust to the impossible—the illusions wiggling and squirming—is another. It points up what an amazing organ we are dealing with.
The system is so complex it begs for a designer. What is more, it serves a higher purpose, giving fair warning that not everything is as we see. Now why should nature build a metaphysical lesson into our seeing process for us?
P.S. If you know who deserves credit for the illusion above, let me know.
