Or not.
It's too... irregular.
One forgets the irregularity after trying to count billions of them.
Ahhhh. I miss this place for things like this! Yes, the non pattern got to me....then I thought I'd count them....after exhausting that....I'd find a face in them or something!
Yes!
They're in a regular, geometric pattern. You don't have to count them.
some copper cleaner first could make them all shiny and regular.
Would you remove them to clean them and then put them back?
Clean them first, then perfectly align.
Unless you clean them too much, and they get different levels of cleanliness.
Perfect alignment would be a problem without a grid.
