This is a recipe for people interested in create a visual decoration for category links using css3 properties.

I could not test if it degrades gracefuly, but it works fine in more recent browsers.

Working but with a few problems

Credit for the css3 rules goes to Mr. Rasmus, nice work.

The category links are floated so text between "tags" won't work.

The css is a bit extense, but the effect is so cool.

I changed the selectors a bit to adapt it to PmWiki needs.

I hope you enjoy it.
