This morning, lets have a link having nothing to do with war, but dealing with violence on an uncomprehendable scale!

Nova offers a short "History of the Universe". It's really just a slider timeline with 14 picture/text segments. However, Birth of a Supernova is a simple animated graphic. And The Local Universe in 3-D uses VRML. (Still haven't figured out how to use it- guess I could read the directions). Open and Closed Universes illustrates 3 different ideas about how the universe evolves. Also, four Quicktime panoramic views in Spin a Spiral Galaxy.

Best of the lot? Not history, Moving Targets nicely explains doppler.
