Procedurally generated galaxy (image-heavy)

Miscellaneous Forums/Blitz Showcase/Procedurally generated galaxy (image-heavy)

is it the same stars in the same spots each time? or is it all random? so if I played your game and wanted to go back to a star... would it still be there the next time i fired it up?

it seems like an external file housing 500million unique stars would be very large.
