Vuvox is a very cool Flash RIA that allows you to create interactive slideshows from your uploaded images, video and audio. Once your media is in the system it can be displayed via a variety of Flash templates. I helped out with some of the templates, as did the awesome Quasimondo.

Vuvox allows you to upload your content via Flickr or Picasa, and has a Facebook widget for easy sharing of your presentations. Check it out here.
