We don't always see what we think we see! For most people the dots in the image below will remain pink, if they follow movement of the rotating pink dot with their eyes.

If that works for you try staring at the black + in the center. The moving dot should appear green.

Then, really concentrate on the black +. After a short period, all the pink dots will slowly disappear, and you will only see only one single green dot rotating.

It's all an illusion. The dot never turns green, and the pink dots never disappear.

Read out loud the text inside the triangle below.

More than likely you said, "A bird in the bush". If so, then you failed to see the word "THE" is repeated twice!

Some cool pictures with double messages.

Just a fun animation.

I cdnuolt blveiee that I cluod aulaclty uesdnatnrd what I was rdanieg. The phaonmneal pweor of the hmuan mnid, aoccdrnig to a rscheearch at Cmabrigde Uinervtisy, it deosn't mttaer in what oredr the ltteers in a word are, the olny iprmoatnt tihng is that the first and last ltteer be in the rgh it pclae. The rset can be a taotl mses and you can still raed it wouthit a porbelm. Tihs is bcuseae the huamn mnid deos not raed ervey lteter by istlef, but the word as a wlohe. Amzanig huh?!
