Change S(i/2) to S(i/2+t) and the stars will blink, shine and fade
u/jpthinker

Thank you u/rodrigo.siqueira ! I take this as a warm welcome since this was my first dweet! And that's exactly what I was trying to do, before I ran out of steam and fell asleep, lol. I remixed this one with your suggestion and figured out a few spots to golf down the extra characters
