Just heard about this "little planets" method for inverting panoramas into a stereographic projection, which is not what I'd expect it to be called. Of course there's a stereographic projection Flickr group-- very cool to browse.

Seems like all you need to do is:
  • Shoot and stitch a complete spherical panorama to get an image with an aspect ratio of 2,
  • Rotate the image 180 degrees,
  • Stretch the image so it's square (aspect ratio 1),
  • Run Filters > Distort > Polar Coordinates..., with the "Rectangular to Polar" option.

I saw one of those on flickr and loved it. It makes me think of le Petit Prince and his little planet.
