Optical Illusions

Okay, I was browsing blogspots and I bumped into one: http://illusionsetc.blogspot.com/ because you know, illusions are tight. SO I clicked on this picture and was led to a gallery of pictures/illusions done by this one person: Jacek Yerka. I believe that's Italian(?). But here's one of them.

These come from the gallery: http://www.yerka.pl/Yerka-pic.html.

And then I came to this horrifying picture.

OMG. I'm doubting that's real, and probably Photoshopped, but it's disturbingly disturbing. Wow. More disturbing portraits and stuff here: http://www.ohlsson.de/dimitri/advertising/DIMITRIDANILOFF.html
Here's another cool one!

And another funnnnnnny one.
