As I promised, here's a few demos of the zope dataminer software. There's a couple of animated gifs which show the working through of the first two examples of the tutorial, and some snapshots of a couple of other examples. http://www.interlink.com.au/anthony/dmcdemo.html They're pretty simple examples, but they start to show some of the really really neat stuff you can do with this software.
