Blinkenlights

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

For brighter lights, try .8 instead of .5

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

u/BirdsTweetCodersDweet

What's up with that weird comment at the end?
u/jylikangas

B.J. is the main character from Wolfenstein and in the demo he is obviously lost. Thus the code is properly commented. :)
u/cantelope
