A while ago I was asked to do a Flex version of WP-Cumulus. Because I don’t know the first thing about Flex, I failed miserably . But the fun thing about open source software is that anyone with the right skills can pick things up and create the version they need. Carlos Carvalha did just that and did a Flex version for use with Drupal. If Flex is your thing, you can download the files from Carlos’ page. Because this is a ‘modified version’ of my WordPress plugin, it is automatically licensed under GPL, and is thus free for you to use.
Carlos’ blog is pretty interesting btw. Definitely the first blog theme I’ve seen that’s built entirely in Flash.
