I think we are agreeing about what WOULD happen looking at points in space from widely differing viewpoints... :blush:
But, if used for Stargate navigation, would that make the system unusable, if every trip you had to re-calculate a potentially large proportion of the chevrons, before dialling home. [Not to mention expensive for anyone filming this.

:evil:]
Having a fixed "symbolic" representation for each "constellation" would remove this problem, and mean that, for example, SG-1 only have to learn a single dial-home address no matter where they go. The Ancients would have only a single problem then - deciding what to put on these fixed glyphs. And oddly enough used 20th century Earth as the viewpoint... :eek7:
