The German artist 1010 has been working in bold colors for sometime now, using minimalist shapes to create strange creatures. But his new works, some of which he showed at the Stroke Art Fair in Berlin earlier this year, manipulate shadow and color in a mind-blowing way.

The colorful canvases are two-dimensional, but appear to be falling into psychedelic sinkholes. Now, he’s taking that approach to the streets, painting amazing optical illusions that look as if you could put your arm through them.
