OK...I didn't look at anyone elses method. I've never used type before...man...really useful for keeping track of a bunch of objects!!!

It's in Barok's post of other people's starfields...if you haven't seen it...take a look. You won't be sorry.
User controlable
It does anti-aliasing among other things....
and pallet switching...
and has a very cool escape sequence...
Lots to learn from this code. It's the last one in Barok's long post.

Yeah, I liked that one too. Except for the errors when using over 2000 stars...
