Mel Chin's "Invisible Aesthetic" takes a plot of polluted land in a landfill near St. Paul, Minnesota and tests six types of plants and various fertilizers to leech up the polluting heavy metals. It's shape is evocative of a crop circle, and the paths through the middle create a geometric pattern, but it seems clear, especially by the title, that this is a work of social consciousness more than what might be typically seen as art. I liked the idea of taking scientific experimentation for the improvement of land and doing something public with it, putting it on display, to create art. There is something about how the picture turned out with the greenest part inside Chin's enclosure that supports the idea especially.
