Optical Illusions
Optical Illusions: this Picture appears to make the coin in the center disappear before your very eyes.
Focus on the intersection in the center of this image and the coin will disappear after 30 seconds.
Because the image is so blurry, If we look at a particular point, even for a short time, everything outside that point disappears, fundamentally changing our perception of what actually exists.
The design is inspired by the Troxler Effect, It was discovered by Swiss doctor Paul Troxler in 1804.
