My university had one in the science building and I played with it a bit. It was able to view various visualizations of data covering the globe (temperature I think might've been one, but I'm near positive weather was also available). They also had imagery of other planets loaded up, so you could spin Mars around to look at different spots.
It's not a very bright display; it is just a projector after all. That video plays pretty well to its strengths in a darker trade show, but in a bright atrium it's much harder to use. It's a little hard to describe, but the "viewing angle" isn't fantastic either. The surface is harder to see than I expected as it gets closer to being perpendicular to your eyes (yeah, obviously, but it seems to lose contrast/brightness or something).
