Panorama animated with Blender

I've written a tutorial describing a technique for rendering a video from a spherical panorama. In this case we are using Blender, an open source 3d modeling package, but other similar tools can probably be used to equal effect.

The way this works is to load a panorama as the background for an empty scene; then set keys for the pan, tilt and zoom of the camera as you would for any normal animation. Here's a link to the youtube video, this is it on Flickr, it seems to embed ok:
