Spiraling rings. Focus on the center. Don't look at anything else or let your eyes drift. Then when the video's finished, look around you.
REPORT BELOW WHAT HAPPENED?
I tried this experiment and found the spiraling rings continuously changing enlarging and shrinking. After watching the full minute, when I looked away the environment appeared to be waving as when the air above the highway appears to wave and the road looks wet.
LIGHT RAYS AND THE EYE
This type of mirage is an optical illusion that occurs when light rays are bent to produce a displaced image of distant objects or the sky. These surprising natural effects of how we perceive our world through refraction of light rays can also be capture on film.
MIRAGE: OPTICAL ILLUSIONS
The source of the French word "mirage" comes from the Latin word "mirage" which means "to look at, to wonder at." Our world is full of wonder and the word "mirror", as in Alice Through the Looking Glass, heightens our awareness of the world in which we live. Do you think the spiral effect that your mind creates after observing this video can be recorded on film? Our mind works in miraculous wonders. This is another image that I found fascinating. I really do love optical illusions.
A STATIC DRAWING THAT MOVES
Doesn't it look just like a spiral? Now take your finger and try to trace along the lines starting from the middle or the outside. What happens? Does it ever spiral? Do your eyes seem to make a reality adjustment when confronted with what is actually on the screen?
This drawing tricks the eye because of the way the circles were drawn. They are not composed of a solid line, but of two lines (black and white) twisted together like a rope. This twisting motion brings your eye into the center of the circle even the there is only one line composed of two parts entwined. If I were an inventor I'd like to know how this illusion could be used in a practical manner.
