Ive been looking at a few optical illusions on the net and here are some of the better ones......

Motion Binding
Benham's Top

This one I had to print out and cut the squares out to believe it!

Not very optical but


Say the following number aloud!
Do it fast!


3
33
333
3333
33333
333333
3333333



Fast! Choose a color and a tool!





Thought of one of each? Don't change the original!

















You answered: Red and Hammer


Didn't you ?!
I thought of green carrot but.....



Also....
How much is:



1 + 5 ?









3 + 3 ?











4 + 2 ?











5 + 1 ?











Repeat the number 6 in your head as fast as possible
for 15 seconds.











FAST !!! THINK OF A VEGETABLE !











Think, think ...













You were thinking about a CARROT, weren't you!?!
Really weird, right !?!?!

This is defiantly the best though....

The one with the a and b square, how can they be the same colour, its obvious there deffenitly 2 different colours.

No they are the same colours - it's an optical illusion - your brain thinks they're 2 different colours because of the way they're positioned in regards to the shadow. Open the image in some sort of picture-editing software and cut out one square and move it next to the other one - you'll see that they are the same colour.

That 'think of a colour and a tool' didn't work for me, I thought of blue and a drill.

Same with the vegetable one.
