3-D Starmap
I saw something like this somewhere (I think it was Deutches Museum (http://www.deutsches-museum.de)) that was similar in concept but denser with map points. The increased density showed more clearly that the (very large) area occuluded by the (very large, but smaller) visible objects is actually cone-shaped -- something that hadn't occurred to me before.
