Minor refinement: Larger resolution so the dots are less noisy; linear index rather than sqrted.

First time this actually saves chars on dwitter...
u/joeytwiddle

Wow, that is the craziest approach I have seen to that problem! But I can't argue with a 2 char saving.

u/yonatan: genius!
u/username

I am very confused. Did I actually bring up shadowBlur again? Have never seen it on Dwitter before.
u/donbright

man this looks so cool.. the JoeyTwiddle effect is one for the books.
u/joeytwiddle

Here are some previous uses of shadowBlur: d/2723 d/3173 d/6820 d/6883 d/9608
u/joeytwiddle

Looks better with x.shadowBlur=j--/7 #glow
