Stefan Eins, foreground, saw a striking similarity between a shadow, center of background, on a facade of Lenox Hill Hospital, and his own profile.

Scenes from Harlem sidewalks: a nasty splotch of green paint, or a clenched-fist image of defiance; a blue blob, or a spot-on profile of President Bill Clinton. As Stefan Eins would ask, coincidence or not coincidence?

Small surprise that Mr. Eins would find order among random lines and spots. In the late 1970s, he found art among the chaos of the South Bronx as the founder of Fashion Moda, a legendary gallery that brought together downtown hipsters and uptown hip-hoppers. But all along he has pursued his own art, teasing meaning from otherwise-random lines, spots and cracks that most New Yorkers pass without noticing.

On walls and window sills, and tucked into neat stacks, are pieces that deal with “the physics of liquid formation,” as he calls some of his earlier work. The pieces were influenced by his long association with leading graffiti artists at Fashion Moda.

He realized that the spots left by quick spray bursts looked lifelike. One resembles a group of tiny, fluorescent pink horseshoe crabs. In another piece, he let green paint flow into white, resulting in a latticework resembling moss.

“The physics of liquid formation are the physics of biology,” he said. “This is a liquid formation. But it is also moss. Same thing. That is why I became an artist, to investigate and find new bounds of knowledge.”
