Street art generally interacts with its viewers, if only by marking things landmarks for those who notice tags or murals. One of our favorite street artists, Ernest Zacharevic, has been making interactive street art of a third-dimension for quite some time. Zacharevic uses installations of readymade objects in order to bring depth to his work. It also allows passerby to jump in the scene, toying with the props and becoming a part of the art.

Now, he’s been up in Norway, taking things to another level, as it were. As part of the Nuart ’13 conference, he’s done a sick new piece on the streets of Stavanger. It features a little boy balancing atop a precarious installation of real chairs. It’s a fascinating bit of optical illusion and a brilliant use of dimension.
