Regime
Vorticity as an object — a sheet, a patch or a filament, inviscid throughout
Every figure drawn under this hypothesis — 36 of them — with the essay each one belongs to and the generator that drew it.
36 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.
