Data visualization videos

Yesterday I noticed a colleague brought an Edward Tufte book to class, but never got around to talking about it. After class I took a few moments to see some of Tufte's latest work online. The ones that stood out the most right now are some Wavefields that mix video of water reflections and data visualization. The text suggests that the ideas haven't been taken as far as he hopes, but the videos are lovely and the idea has a great depth that will keep me checking his site.
