Hidden Numbers

A quickie! Look how by adding the number 8 to the number 4, you can get any number from zero to nine. Kinda neat, but not our most amazin illusion. For that, you'll have to scour the navigation bar on the left, until you find the perfect optical illusion!

Arrows by Serhiy Grabarchuk Can you find in the illustration on the left two pairs of arrows, the respective tips of which point two exactly identical horizontal distances between these tips?  A tip of each arrow is meant as one shown in the diagram on the right.

Optical Illusion Chalk Drawing - The Sidwalk Trap

This is one of my favorite items here. Wow. Send this one to your friends!

How would you like to be walking down the sidewalk and then suddenly fall into a hole like these guys? Take a little closer look at who has fallen into the hole. It's tough to tell but it looks like George W. Bush and Cheney have fallen into the hole.... and is that Tony Blair looking into the camera? Regardless, this sidewalk optical illusion is just downright incredible!

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!

The Cafe Wall Illusion - a Photo

Look at the optical illusion that is presented on the wall of this cafe. You'll find a similar optical illusion in our optical illusion desktop wallpaper section. It's only a matter of time before Trading Spaces uses this idea to create a room full of optical illusions.

Circle or Spiral Optical Illusion 2

This is another great example of concentric circles that look like a spiral. Just like the previous image, you'll see that the coloring of the circles really leads your eye right to the center of this optical illusion. You can use your finger to trace the lines of each circle, just don't get your fingerprints all over your computer monitor! The red and black diamonds further add to the illusion, and even give the illusion some depth, because they are drawn in perspective, with the center as the vanishing point. This type of perspective is called one-point perspective and involves two sides of each object pointing to the same spot on the page. This is one of my favorite optical illusions!

Clinton Gore

Glance at this picture really quick and you may have thought that it was Al Gore standing behind Clinton, but actually it's clinton's face with Gore's haircut. Just a little eye trick for you before we move on to another cool optical illusion.
