edit to add: I'm not a chemist or scientist but I find this sort of thing
fascinating.

edit again: This site has a lot to view. If you go rambling around, let
me know if there is anything you especially liked. K?

1. There are also fullerenes and nanotubes

of different shapes and structures. For example, some nanotubes are conducting; others are not. A web search should easily turn up images.
