Moiré #25 by Liz Deschenes (American, b. 1966)
"Moiré (from a French textile description) occurs when two patterns (meshes, concentric rings, grids, etc.) are overlaid, creating visual interference at their intersections. To make this work, the artist exposed a sheet of perforated paper against the bright white expanse of an open window. She recorded two exposures, and then superimposed the two negatives slightly off-kilter on an enlarger."
