More optical illusions...

Stare at the central dot, and move your head forwards and backwards.

The lines in this picture below are completely parallel would you believe?

Can you see dark blotches on the white 'junctions' in between the corners of these black squares?

Which way is the wheel turning!?
Focus on the red dots and follow them round... it appears to be rotating anti-clockwise. However, if you follow the yellow dots round instead, the whole wheel will be turning the other way! - clockwise!

There's certainly something very ambiguous
about which way this is meant to be up...

cool illusions. try these

Jesus Optical Illusion Image

What you should do for the black and white optical illusion image above:
Stare at the center of the image above for at least 30 seconds. Then look at a blank white wall, or a peice of paper. What do you see? On this page you'll see that the after image of the black and white image above is much stronger than the one in color below. Take your time, sometimes it takes an additional 20 seconds before your eyes can really focus on the after image.

Now, instead of black and white, lets try color! For the first optical illusion image above you are looking at a human face straight on. Even though it is much more fuzzy of a picture, your mind has an easier time filling in the blanks. Can you tell who this man with a beard is above? It isn't just any old man, it's Santa! You may need to stare at the Santa optical illusion longer than you stared at the Jesus optical illusion in order for the after image to be visible to your eye.
