PUBLIC MARKS with tags css & favicon

I've had this JSFiddle from CSS Wizardry open for like 2 weeks in my browser. I kept thinking about it, because before that I got an email from someone asking about essentially the same thing and it stuck in my head. They were wanting to insert a favicon next to links and use only CSS to do it. Unfortunately I haven't found a way to do exactly that, but using some jQuery we can do it pretty easily.

Ajaxflakes nous offres une liste d'environ 100 générateurs à la mode Web 2.0. On y retrouve des générateurs de badges, de boutons, d'images de chargement, de noms Web 2.0, de menus, de css, de noms de domaine, de codes, de metas, de mots de passe, de sitemap, et j'en passe beaucoup... Bonne trouvaille ;-)

For links that point to external sites, what if, instead of showing a generic 'external link' icon, we showed that site's favicon?
