visualisations of the web

Another nice tool for visualising the activity of the web. This one creates colour coded diagrams based on the type of tags on sites or pages - images, divs,tables etc. It creates very attractive and varied visualisations, and is available on a blog here. ALong with processor it provides an ability to create simple graphics (not quite so simple with Processor)that are visualisations of the flow of type of information.
If there are more around, please let me know!
