I thought of this topic immediately this past weekend - we had a photography expo, and some local photographers showed and sold their work. One woman whose name I now forget had some fascinating stuff - colour photos of various flowers shot *through* a variety of solid pieces of stained glass (which she also made). Some of them were obviously flowers, but with odd colourations, and some ended up just seemingly random, well, abstractions of something.

Very interesting work, although I don't think it sold well from the look of her booth.
