Yeah, the 3D angle continues to be a pain in the chairdock. As it stands, we've got things like Celestia, The_Sky, Starry Night, etc. that aren't quite yet adaptable to our fannish purpose. The Whitten Starmap site is purpose-tailored, but doesn't yet have access to a sufficiently large database of stars and other cosmic objects of interest to really play with on a large enough scale. For now. The ESA's Gaia mission database, once that finishes up being built...that'll help things immensely.
