I initially tried with falling raindrops but that only confused the effect
u/lurifax

Nice effect!
u/cantelope

this is so great
u/joeytwiddle

Better performance: i=43e Stronger effect: F*F/10

u/akm

woah, thats an awesome dweet and some crazy codegolfing!!

If I add that filter, flames start coming out of my laptop!
