1010 is both a gallery and street artist in Germany with a passion for surreal figures, geometric illusions and other visual trickery. Recently finished working on this impressive new piece somewhere on the streets of Hamburg, Germany for the Knotenpunkt Festival. The simple technique looks a lot like the work of a growing number of paper artists who are creating similarly layered artworks, but 1010 is reproducing that 3D technique on the flat. Even though they’re being painted on concrete walls, these pieces look real enough to reach inside and touch some color. This particular series of optical illusion ‘holes’ spans both sides of his portfolio – smaller-scale works are framed and hung in galleries while larger-scale installations are set in rough exterior urban landscapes.
