Can someone create a WordPress CSS demo like this?

Hey guys,

I just saw this cool tutorial…
Understanding Joomla / Mambo CSS in 5 minutes -> http://www.joomlart.com/tutorials/templates_tutorial/understanding_mambo_css_in_5_minutes.html

And I give it a 5/5…

I searched for a similar one on WordPress codex… dint come up with one (or maybe I was blind)

Someone, plz try to create such a demo/tutorial for WordPress… Puh-lease…
