#electric #neon #rain, as requested by u/donbright

u/f8f82804

This is the best solution I found to having them not be too fast; we only change the pattern 7 times a second. Using S() means there are occasional patterns in the drops. Change to y=99*Math.random() to see the difference.

hee hee, thanks
