I put together a blog.
I've tried to style as many elements of the default install as I can.
(NuclearMoose described it as "an explosion in a crayon factory!").
Hopefully it will persuade a few people that you don't need to resort to tables and html to get effects, you can do it all - and more - just using CSS.
I hope it's useful :)
(Because my aim was not to alter any other code, those posts may occasionally drop off the front page. I'll try to remember to republish them with new dates)
