This image is constructed by traversing the 2D image space in parallel with the 3D RGB colour space, in order to assign at each step a unique colour to a unique pixel.
The traversal is driven by the greedy algorithm (https://en.wikipedia.org/wiki/Greedy_algorithm) and randomness when choosing among equally near neighbours.
Visually, the traversal proceeds along a continuous contorted path through adjacent neighbours, until it reaches a dead end, at which point a jump occurs to the nearest location from where the next path can start.
