This is related to recent forum post about this without using any extensions and I wanted to test feasibility of that. To my surprise it seems to run fine.
Only extension used are Array to store positions of stars and Mouse object(by Cellosoft)+Window Control to make easy mouse look.
This example will create infinite repeating starfield that you can fly in any direction. Its not commented, but simple events should be easy to understand and the complicated ones...well magic happens there(basically just some math).
