Cumulus allows you to display your site's tags using Flash that rotates them beautifully in 3D. It works like a regular tag cloud, but is more visually exciting. Cumulus requires a JS script called SWFObject. This script is licensed under the MIT license and can't be hosted on Drupal.org. So, you need to get the file from http://pratul.in/files/cumulus.js OR http://pratulkalia.googlepages.com/cumulus.js and put it in your Cumulus folder in your modules directory. Cumulus is based on the WP-Cumulus WordPress module by Roy Tanck (http://wordpress.org/extend/plugins/wp-cumulus/)
