Good day.
Looking to make a random pattern with different size....something like the 95 Acer aspire pc.
They had a random pattern of holes at the case and monitor https://dn790007.ca.archive.org/0/items/ACERSRCCD/Acer%20Aspire%20%281996%29%20Windows%2095.jpg

Is there something like this in Moi?

Tnx!
