I really like the images produced by this little gizmo (link deleted for safe browsing after it was compromised.)
In case you can’t be arsed following the link, it turns websites into geometric representations, in a most charming manner.
Here’s the legend, if you care.
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
grey: all other tags
