Beauty in Disease?

My son found this leaf of Bigleaf Maple in the woods near our house and brought it home. We both found it beautiful. Some sort of fungus or lichen (black splotches) seems to have affected the rate at which chlorophyll disappears and reveals the yellow pigments that were previously masked by the green. Seems like a good model for camouflage clothing. Click on the photo once or twice for an enlargement and a better view of the details.
