So, I was browsing through the Mental_Floss daily Cup o' Links and found a link to this Danish artist named Peter Callesen. He makes this amazing art out of a single piece of paper. Click each of the pieces to enlarge.
I noticed one of his things is the negative space left on the paper looking like something alive, while the cut out has been squished and shaped to be bones. Very nice.
Check out his website for even more brilliant pieces. These are my favorite.
