online resources for fulldome production

Tried out a few options of the many many resources available on the internet, like the ones mentioned in the Small Planetarium Yahoo Group.

1. Tried the dome-masters available at spacetelescope.org - unfortunately, only one of them is a bonafide animation - others seem to be just a single hubble image rotated around the centre of the dome. I can do simple rotations myself!
2. The Science on a Sphere program links to many hi-res movies - 2048x2048 on the public ftp site ftp://public.sos.noaa.gov - these movies are generally suitable only for projection on the sphere as designed, but some parts of some of the movies can perhaps be adapted for fulldome, like animations of LCROSS hitting the surface of the moon etc. In most cases, such animations may be available for fulldome from other sources, so it may not be worth the hassle to try this out. An interesting sidelight while downloading deserves a separate post.
3. Some youtube videos like the ones from jakimsuk are available in 720p and seem to be prewarped for 4x3 projection. But the material is probably copywrited, like Spitz trailers and so on.
