Regime
Stated in the wall's own variables — a friction velocity, a roughness, a kappa
Every figure drawn under this hypothesis — 49 of them — with the essay each one belongs to and the generator that drew it.
49 figure placements state this regime. The strip along the foot of every figure names two things — the model that produced it and the regime it holds in — and this listing is read back out of the finished drawing rather than from what produced it.

- A larger sphere overtakes its neighbour and leaves on the line it came in on — creeping flow, Re → 0; one sphere 2% larger; contact roughness as marked · reciprocity
