I agree with Mark. Nifty shots. Don, have you ever done a butterfly wing? I can still remember looking at one through a microscope (grad student, Biology) and being amazed at the patterns and colors.

Amazing stuff! This microscopic photography is really fascinating. A couple of weeks ago I put together a Powerpoint presentation for my S.O. with a ton of her slides of various tumor cells. I found a lot of the images really stunning strictly from an esthetic standpoint. Your crystal photos impress me in a similar way.
