Optical Illusion Pictures #3
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.
Weird Impossible Shape Illusion
Here is yet another impossible shape. As always, you'll
notice that the shading ads to the effect of this optical illusion.
Here's a quick memory test: Take 30 seconds to look at this optical
illusion, then look away from the screen and try to draw this optical
illusion on paper. It's pretty tough unless you have a photographic
memory!
