I’ve been noticing a lot lately, that a grid can be based on absolutely anything that makes some sort of sense. I wish the flexibility of using a grid that’s not some prefab 960 subdivisions was teased apart more. I’m noticing similar for degrees of isometric-like shapes .. they really needn’t be 30 or 45 degrees.
I’m investigating these things myself as I decompose certain works I like, but, I’d love to hear someone else speak to this.
