Anyone who works with Flash should find this interesting. Blender user Dennis Ippel has created a script which can convert Blender objects in Flash ActionScript 3.0 objects. This allows the creation of realtime-3D rendering within Flash (which is more typically used to render two-dimensional vector imagery). For more information, visit the exporter's official page, or its wiki entry.
The most useful information can be found on the official page, including a setup tutorial and a small demo created with the script, showing a rotating torus (pictured). Supported Flash 3D engines are Papervision3D, Away3D, and Sandy 3.0, and it is compatible with Windows and Mac OSX. Thanks to Dennis for this useful resource!
