Various artists

Stanford Slutsky creates abstract artworks, that can be described as geometric optical illusions. The important part of his artworks are incremental, harmonic gradations or hues, which intensifies the optical illusion of the three-dimensional effect. Systematically organized shapes lead into complex patterns of shapes.

Among other artworks there's a series of judaic artworks with impossible David stars. Some of them you can see below.
