A follow-up to Andy's previous explanation of his compound grid layout in which they explain their logic behind a 4 + 5 compound grid a bit more. It's neat, but this description is what really caught my eye:

Think of each column as a beat. When you drum the cadence of 12 evenly-sized columns with your fingers, the rhythm is monotonous.

That's a nice way of framing a layout. I'd like to give it a try in reverse one day: think of a drumbeat I like and work out what grid layout is equivalent to the hits and gaps, then see if it could be the foundation to a site. Sounds like fun 🥁
