Over the weekend, we visited with
Professor David Dailey at Slippery Rock Universtiy in Pennsylvania. A professor of computer science, Dr. Dailey has a build one of the largest collection of public domain images, which he scanned into a database for public use. It's clip art on a massive scale, and
you can browse the collection here. I liked this one of a Bactrian camel, a souvenir of our time in Central Asia...
