Light from a prism in the National Museum of the American Indian Originally uploaded by Major Clanger.
Aha! All attempts to blog from Washington DC were ruined because the blogger API changed, and I needed to reconfigure Flickr. Sigh. I paid $10 per day for Internet access at the hotel :-( This is a test posting: Light from a prism in the National Museum of the American Indian. One huge blog entry with lots of pictures to follow!
