Work-in-progress version 2.0 of the Flash movie that powered WP-Cumulus.
Please note that this is not a drop-in replacement for the Flash movie used in the now-discontinued WordPress plugin. It was created to be more generic, and no longer uses an XML format that resembles WordPress's tag cloud html.
Please feel free to write a new plugin wrapper for WordPress or any other platform, or to convert this into HTML5/Canvas or any other suitable technology.
