Drupal Icon Sets

There was a push a while ago to get Drupal to use the tango icons, which was then pushed back, since Tango's license is CC and not GPL. I don't fully get the distinction, but here are the GPL icon sets I have found:

* "Lullabot Icon Set #1":http://www.lullabot.com/articles/free_gpl_icons_lullacons_pack_1
* "Morten's Iconify Module":http://morten.dk/blog/mortendk/iconyfi-alpha-pixels-dot-03
* "Mark James' Mini famfamfam set":http://www.famfamfam.com/lab/icons/mini/

Other nice free (but not GPL) sets

* "Drunkey Love":http://www.el73.be/drunkey-love/downloads/
* "Mark James' Silk":http://www.famfamfam.com/lab/icons/silk/
