Amanda Hughen's drawings on Mylar take their images from biology, architecture, geology and topology. "Managed Disclosure" is purely abstract in that the forms don't literally refer to any of the sources that inspired them. Yet the piece is vaguely topological and, less vaguely, biological, suggesting cell division, mapping of terrain and the complex petals and flowerheads of certain plant species.

It isn't any of these things, however. It's an image that functions on its own, and as such it represents purely the things that happen when complementary and contrasting colors are put together with lines borrowed from various academic disciplines from mathematics to biological illustration. Like the San Francisco artist's other works, "Managed Disclosure" is aesthetically seductive; smart in its selection of bits of the world, it is singularly beautiful in the everyday sense of that word.
