Nanotech Vision Visualized

Eric Drexler's vision of nanotechnology was once the main such vision, before nanotech became a popular buzzword, debased to mean anything with nanometer scale structures (enabling a huge national research initiative on the topic to be funded by just relabeling existing research).

Drexler has continued to elaborate his vision, and he now has a (86MB) movie to help you visualize it, available free to download.  Beats the summer SF flicks as a thought-provoking vision of the future.
