SKIN 2 BY MEHMET ALI UYSAL

Built for the Festival of the Five Seasons in Chaudfontaine Park, which lies on the outskirts of Liege, Belgium, a giant clothespin sculpture appears to be holding on to a mound of dirt and grass.

Designed by Turkish artist Mehmet Ali Uysal, a professor of art at the Middle East Technical University, the giant sculpture is just one piece in a string of Uysal works that rely on flawless illusion.
