Can't let this thread go without my personal hero:






Maurits Escher, born on the 17th of june 1898 in Leewarden. He and Oscar Reutersvärd are the pioneers and masters of portraying impossible figures, some of Eschers woodcarvings are awe inspiring.

I like M.C. Escher's artworks, too. Here is my favorite of his.

It creates the same aftereffect. It will work to different levels depending on the person.

[Rayaan]

The one that I posted seems to work better for me, though. But yeah, like you said, maybe it differs for different people.

Here's another illusion:



Here, you see a picture of a circus, and if you tilt your head to the side, you'll see the face of a clown - like this.

Here is another;



What animal do you see?
