I just ran across a series of videos called 500 Nations, narrated at least in part by Kevin Costner but with a host of native people involved. It is about the histories of native peoples of North And South America, with computer models, photos from museums, etc.
I figure that probably many of you have seen it, but since it had gotten by me until now, maybe someone else who reads this would like to know about it, too. The first segment on Google Video is here and there are links to the rest, but you can probably buy it on DVD. I have only seen a little of it, but the research appears to have been extensive. If you've seen the whole thing, let us know if you liked it.
