Ten years ago I co-wrote one of my first web design books, HTML Web Magic, whereby one of our mottos were "HTML is your friend" so that new web designers wouldn't be afraid of code.
Now there's a site that shows just how beautiful HTML code can be by visualizing web sites as graphs. Each color on this graphical flower tree represents certain HTML code. As you can see, it's mostly blue here because blue represents links and I've been linking to a lot of things. It's cool to see the existing graphs created for CNN, Google, and Yahoo. Try it out on your own blog!
