Another 10 Amazing Optical Illusions
Following the popularity of our Top 20 Amazing Optical Illusions list, we are presenting you with another 10.
10. Leaning Tower Illusion
The two images above are identical, yet the tower on the right appears to be leaning more steeply. The reason for this is because the visual system treats the two images as if part of a single scene. Normally, if two adjacent towers rise at the same angle, their image outlines converge as they recede from view due to perspective, and this is taken into account by the visual system.
9. Color Perception
Believe it or not – the pink spots in the image above are the same – if you don’t believe me, open the image in photoshop and compare them.
8. Inverse Image
Stare at the center of the image above for about 30 seconds then immediately look at a blank white wall or a piece of white paper. Stare at the blank paper and an image will emerge. The more you stare, the clearer the image becomes.
7. Instant Gratification
This one works immediately – stare at the dot in the center of the image and move your head back and forth – the rings will rotate.
6. Straight Lines
The image above is composed entirely of straight lines. If you don’t believe, try using a ruler to test it.
5. Believe it or not
This one is amazing – the blue and green lines in the picture above are the same color.
4. Sacred Heart Illusion
Click the image above to open it as its full size then slowly move your head away from the image.
3. Moving Squares
Move your eyes around the image above and the squares will appear to rotate.
2. The Hollow Face Illusion
This excellent video clip illustrates a brilliant optical illusion known as the Hollow Face Illusion.
1. Monster Magic
In the image above, the two monsters are the same size.
