my del.icio.us tags
Tag Roll
A tagroll offers a visual reference to all tags used within an account. Once your collection has a moderate number of links, and you have deployed a variety of tags meaningful to your content, then it provides a more interesting way to view what you have collected in your account.
Again, this is generated all within the del.icio.us site, under "settings". It generates a few lines of JavaScript that can go in any web page.
See a screenshot of settings used to generate this display.
