paper... scissors... ROCK!
Maaan... I can't believe some of these artworks are made out of plain white paper.
These are apparently the work of one Peter Callesen, from Korea. The first link is to a blog that has posted the pics, which is easier to navigate than the artist's actual site.
(Also, if you scroll way down, you can see the best blog comment I've ever seen: "Mond of the Lord!!! This is fkn awesome, biatches!")
