In light of the conversation about the new super-sensitive digital SLRs and astrophotography, CJ sent along this article on the Sloane telescope, an 8 foot mirror with a fairly wide field that's done the automated Sloan Digital Sky Survey:
The SDSS used a dedicated 2.5-meter telescope at Apache Point Observatory, New Mexico, equipped with two powerful special-purpose instruments. The 120-megapixel camera imaged 1.5 square degrees of sky at a time, about eight times the area of the full moon. A pair of spectrographs fed by optical fibers measured spectra of (and hence distances to) more than 600 galaxies and quasars in a single observation. A custom-designed set of software pipelines kept pace with the enormous data flow from the telescope.

That's an amazing setup. I'd love to see an interface to the survey data which allows you to visually traverse the database in three dimensions.

Jeff, I'm sure such things exist, it's just a matter of finding them and their data sets in the same place.
Speaking of which, are you familiar with Astrometry.net? Feed it a picture, it tells you where your scope was pointed.

Dan--I have actually done some work with a fellow who does demos of Battelle's Starlight 3D analysis application. I've queried him to see if he's used one of these datastets before and, if not, to see if he can.
Haven't used the Astrometry.net site before. Will take a peek.
