Bridget Riley uses color and tessellating patterns in her paintings. The colors in Nataraja, 1993 feel chaotic to me but the lines provide the harmony. I used a script to add a different kind of tessellation on top which breaks the whole thing:
Something about the curve of that not pipe reminded me of the curves in Audubon's birds. This ruined image started out as Audubon's American Crow, 1861.
After my experience ruining squares, I wondered if images of color field paintings could be ruined with triangles even with no sharply defined structure. So I tried the same thing with some images of paintings by Mark Rothko.
Here are the three I picked: No. 61 (Rust and Blue), 1953. White Over Red, 1957. And No. 46 (Black, Ochre, Red Over Red), 1957.
