I’m digging this kinetic sculpture by Swiss artist Markus Raetz (previously) that creates the illusion of a rotating head using a series of silhouettes cut from metal panels. Most of Raetz’s work involves aspects of perception and illusion, more of which you can see here. (via Sploid)
Photographer Allard Schager shot this perplexing photo while looking up the Stairway of the King of Aragon, a stairwell carved into a steep cliff face in Bonifacio, Corsica, France. I’ve looked at it carefully half a dozen times and still get confused as to which way is up or down. Totally wild.
I’m really enjoying this rural intervention (?) created earlier this week by Daniel Siering and Mario Shu in Potsdam, Germany. The duo wrapped a tree in plastic sheeting and then mimicked the background landscape using detailed spray paint strokes to create the illusion of a tree cut in half. It reminds me of this mirror installation by Joakim Kaminsky and Maria Poll. (via Street Art Utopia)
