Blinkenlights

u/joeytwiddle

Inspired by (but barely resembling) the Arabesque screensaver on macOS
u/joeytwiddle

For brighter lights, try .8 instead of .5
u/joeytwiddle

Whatever number you choose, one lights always blinks regularly. For 97 it's the orange light in the lower right.

For 321 there is a yellow light giving a double pulse
