The San Francisco Museum of Modern Art is presenting "Illegal Art" an amusing collection of provocative paintings:

Some of the more creative paintings are:
Aric Obrosey
"Oily Doily"
Acrylic on mylar, 31" x 24", 1991
In this lace-like painting, Aric Obrosey combined three oil-company logos with the shine and shape of an oil spill. The doily's border is comprised of tiny droplets, which he says "symbolize the spilled oil breaking up and spreading outward." Although Obrosey meant to represent the oil industry's environmental disasters, he was invited to feature "Oily Doily" in Oil Patch Dreams: Images of the Petroleum Industry, an art exhibit sponsored by Texakoto and other oil concerns.
