The Skin-Crawling Spiral

Please wait a moment until the spiral has finished loading.
When it's spinning smoothly, stare at the center of the spiral
for about a minute. Then look at the back of your hand...
It will appear to be twitching and moving, as though
bugs were crawling under your skin!

Short-Circuit Your Brain

Look at the chart above and say the COLOR of the word,
not the word itself.

Why is it so difficult? Because the right half of your brain
is trying to say the color, while the left side of your brain
is trying to say the word.

Looks like a spiral, right?

Wrong... It's a bunch of independent circles

Moving Sircles

Stare at the cross and quickly move your head
forward and backward, towards and away from the
screen. The circles will appear to be moving. 

Spinning Wheel

Focus on one wheel, and you see it's not moving.
But move your eyes around from one wheel to the
next, and all of them appear to be spinning.

Test Your Blind Spot

Test Your Blind Spot

Alright, right now you can see both an x and circle. Close or cover up one your left eye. Now SLOWLY move your head closer to the screen and stay focused on only the X. As you get about six inches from the computer screen, you'll see that the circle has actually disappeared. You just found your blind spot!

You'll find that different people have their blind spots in different areas, so have your friends try this eye trick and see how far away from their screen they were when the circle disappeared.
