   Hi all,
   
   a total-beginner question...
   I'd like to reproduce the old windows98 stars screensaver :
   stars are emitted in the center region, and moved / scaled up towards the edges of the screen.
   
   Seems really simple but i'm kinda lost with all thoses functionalities...
   
   Thanks for your help !

   Here's one hack to get you started on your journey to the stars. Notes: The last number in velocity controls the speed of the stars and instead of a dead zone, I just have the particles live for 4 seconds--enough time to make their trek across the reaches of space (or from z = 1000 to the viewer, whichever comes first). Not the most efficient but, hey, neither is this starry universe of ours.
