Thanks to all 10K plus of you for checking in. I hope you like(d) what you see/saw.
Commanvil.... I understand your suggestion, but I find that the termination of the photons after a few cycles to be preferable. Allowing them to live longer only to devolve into a disorganized cloud, seems to me to be less satisfying. You, however, can always set the photons to whatever life span you wish.
You can always set the life to 99999 so it lasts longer (I'm talking about the center thing)
Pharaoh... True, though I do like to watch them slowly die out, too.
If you want the photons to stay for longer, just increase their life
