Hello,
i have adapted the WP-Cumulus http://wordpress.org/extend/plugins/wp-cumulus/, into a widget for SS. you can see a demo here http://www.futurs-ingenieurs.webou.net/blog/ (it's the 3D tag cloud). I submited the widget a month ago, and it's not yet added to official widgets. And im wondering Why?. If there's any problem or any bug, please let me know. This is the link for the widget:http://www.futurs-ingenieurs.webou.net/widgets_cumulus.tar.gz
Thanks.
