Ingenious Sculpture Creates Illusion of a Turning Head

This ingenious kinetic sculpture features two spinning arrays that form the silhouette of a turning head in the negative space between them. According to the 2011 video’s uploader, fulukuku, the piece is by Swiss artist Markus Raetz. The sculpture does indeed fit with Raetz’s body of work—the artist is known for drawings and sculpture that deal with perception and illusion.
