NOTE: Please use caution if you are prone to queasiness or other problems with illusions. Also note: some of the images are animated, or appear to be moving.

Stare at the red dot long enough, and the grey stripes will disappear.

Believe it or not, these lines are straight and parallel.

The two birds in this image are identical. Not just in size and shape, but in color too.

These “fish” may appear to be wiggling, but the only thing changing in this animation is the color.

What’s your first impression of this image? Yellow arrows pointing left, or green arrows pointing right? There is no “correct” answer, but different people perceive this image differently at first.

Another “false spiral” — actually a series of concentric circles, hard as it may be to believe. To prove that there’s no spiral, try tracing your finger around one of the circles. You’ll see that it never moves inward or outward.

Stare at the center of this simple animation and you’ll be convinced you’re seeing a green circle moving around the edge. But are you?

Lean up close to your monitor. What does this image say?

Try stepping back a few feet. What does it say now?

What appears to be a gaping chasm in the middle of the street…

Try moving your mouse pointer down across this image, following the pointer closely with your eyes. You should see a rippling effect moving through the picture — even though it’s a completely static image!

A variation on a classic illusion, this cat can be perceived as rotating in either direction. With practice, you can make it switch at will!

Believe it or not, this image is not animated. The effect persists only in your peripheral vision; if you focus on any one of the spirals, it will stop moving.

More bang for your buck! This three-in-one illusion includes a false spiral, an impossible Escher-esque structure, and what appears to be a seriously warped floor…

Can you unweave this web and find the hidden word within it?

Can you tell where on this curve the lines are the longest, and where they are the shortest?

Are the walls of this house facing outward, or inward?

Which of these two dots is in the true center of the circle?

Can you tell which of these cars is the largest?

Which square is a lighter shade, A or B?

Here’s a simple one. Are these two rows of squares perfectly parallel?
