// XOR the position on the ring with a slice of the clock and keep three bits.
// There is no randomness in the language and none is needed: a motif walked past
// itself by a stride that does not divide the perimeter reshuffles rather than
// slides. Reads as a machine thinking.

// `p` below is distance clockwise round the border from the top-left, written
// out in full because there is no way to name a subexpression -- which is why a
// small effect is a long line. `2*cols + 2*rows - 4` is the whole ring.
