Whose the genious behind the art??!

I've been looking all over, I can't find this artist. I wouldn't be suprised if many of you saw some of these paintings/illusions around the net. I've been looking for his name so I could possibly order a print or poster. These pictures are amazing. You can view it by downloading this file and seeing it as a slideshow on powerpoint (im not sure what to do on a mac)

NO VIRUS, take a look, I promise you won't regret it.
I just wanted to share these and ask around if anyone knows who this guy is...


thanks!

Oh, I think I saw it on Digg. One sec...

uh, can't find it. But search illusion and sort by most Diggs and you should be able too.
