Optical illusions . . .

I decided to find some optical illusions and post em' here!




Are the lines below straight or are they curved?


Try putting a straight edge against the lines on your screen to test your conclusion.

The following pictures are NOT animated.

spinning wheels

moving petals
three columns of waves
moving lines of leaves
Your eyes are making them move. To test this, stare at one spot in each picture for a few seconds and everything will stop moving; OR look at the black center of each circle in the first picture, and it will stop moving; but when you move your eyes to the next black center, the previous one will move after you take your eyes away from it.


Look at this Image and say the color of the text aloud.
