While perusing ONLINE, which bills itself as "The Leading Magazine for Information Professionals" (who knew?), I discovered SciVee. The National Science Foundation and the San Diego Supercomputer Center teamed up with the Public Library of Science to create SciVee, which contains video presentations by scientists describing the work they have done for their scientific papers, and more recently, work not related to scientific papers as well.
Basically it's a YouTube for science. Bet it has some interesting stuff!
