Two cell types swap places with a neighbour when the swap lowers adhesion energy (Metropolis). Like-like contacts are stickier than unlike ones, with strengths set by the seed.
Tap to scramble a patch. The same ?seed= always gives the same run.
LITSteinberg’s differential adhesion hypothesis; Graner & Glazier (1992). Cell counts must be conserved, or the page throws.
