A list apart was probably one of the first feeds I added to my RSS reader, and up until this day I enjoy reading the high quality articles.
Just last Tuesday they published an article around progressive enhancement with css, which covered a rather funny example from Andy Clarke's site, which is completely black and white in IE6, along with modified low-fi images.
I couldn't resist doing this myself as well, so if you hit this site using IE6 now this is how it will look like:
.
The code:
- <!--[if lte IE 6]>
- <style type="text/css"> body { filter: gray(); } </style>
- <![endif]-->
