None however, that I can find, offers the functionality included in today’s invention.
Instead of doing the standard thing of compressing stars into meaningless, 2-D constellations, the app which I envisage would portray the stars as dots with different diameters.
Closer stars would have a larger diameter.
This would also allow stars at a common radius to be shown on a translucent sphere (perhaps with different colours for each).
It would then be easy to animate the simulated movement in a given direction from sphere to sphere (and thus backwards in time).
