Here's Román Cortés' Homer, animated to show the structure. I haven't done anything to Román's amazing work other than to annotate the divs with ids and add a bit of jQuery to show them in sequence so that you can see the characters being added one at a time.
Click your choice of fast or slow animation:
Román also made a George Bush.
PS: if this doesn't look right for you, it may be that you are on Linux and don't have the Verdana font. You can install it from the msttcorefonts package.
