@superstar: The artist who made that "tree face" is in my school. She didn't want to sell that; she made it for her mother. Then she was pressured to make copies by nearly 3,000 people all wanting a print.

This tree face image is found on 905 different webpages.

And the other one comes up with 44 results. Interesting site, Arthur. Also interesting that the tree is much more prevalent.

Three of my favourites.
The first one apparently has two triangles of the same size, but one of them is missing a square even though it is made from the same pieces.
In the second one, the squares labeled A and B are actually exactly the same colour.
In the third one, if you stand far enough away from the screen, the faces apparently switch positions.

I don't understand the middle one, with the little checkerboard. What's supposed to be happening?

And this video is tricky

He explained it. The two squares labeled A and B are actually the same color.

I'm looking at the middle one and well, ;D my eyes are telling me thy are not the same color. The letters A & B are the same color yes, but the square where A rest inside of and B rest inside of seem to be too total different shades on the spectrum of gray, one is way lighter and one is waay darker.

Anyone else seeing the same color, I'm tempted to do print screen and get the pixel color information.

[edit]
Wow, I did print screen and got pixel data and wowww, they are the same color

[edit]

And that video link posted about crazy diamonds, wow thats real too. I know about some illusions thus I created this thread but I was thinking perhaps, maybe video editting. But I print screen again, selected out the piece the moves around the board placed it on top of all three different shades and the same effect was produced. Cool stuff. Ummh camoflouge technology, somehow?

Posted in 2002, you have a good memory.

The tricky diamonds video, I printed out the board and tried it in front of me and if works the same, quit crazy to see it right in front of you.

Yes. It's old. Most of the good ones are old. But that doesn't stop them from being my favourites. :)

Here's another oldie but goodie.

I made one once; in the right lighting (ie: head not casting a shadow on itself, which ruins the effect) it actually works pretty well! Do a Google for "paper dragon illusion" for printouts.

Hah! The latest Afghanistan version of the Tomb Raider game has a "nude patch" that reveals Lara's face and several inches of arm! pg-13 indeed.

Which way is she spinning?

It seems pretty obvious to me she's spinning on the Y axis.

Counter-clockwise. The shadow gives it away.

The shadow gives it away.

When I "see" it as clockwise, the shadow doesn't look right, so I guess it's true.

On another note, why does a mirror reverse left and right, but not up and down?

It preserves both left/right as well as up/down. It's the Z axis that's reversed. Imagine you're looking at the back of your head when you watch your reflection raise its right hand.
