Oh, pretty. Marcel Salathé has created a java applet that builds a network of your blog (or any other website) based on the internal HTML. I think the big "flowers" are the articles.
What do the colors mean?
blue: for links (the A tag)
red: for tables (TABLE, TR and TD tags)
green: for the DIV tag
violet: for images (the IMG tag)
yellow: for forms (FORM, INPUT, TEXTAREA, SELECT and OPTION tags)
orange: for linebreaks and blockquotes (BR, P, and BLOCKQUOTE tags)
black: the HTML tag, the root node
gray: all other tags
If you do your own, be sure to pay attention while the graph is building. That was cool.
