IdN v19n4: Shapes-in-Pattern — Shaping Their Own Patterns
Patterns are easy, right? Just come up with a nice little design, then copy-and-paste it ad infinitum. Well, nothing could be further from the truth.

It is a lot more complicated than you might think – but the results can be deeply satisfying.
