I recorded this show back on Dec 27th, but had not watched it until tonight. Link below tells about the show, but I cannot figure out how to provide a link to actually watch the show as a video on the internet. Must not be listed as part of the Smithsonian Channel videos. This was a pretty cool (no pun intended) show!

They do have a lot of other videos available on their site...some in Full Episode, like this one
