Twelve words scattered on a plane, and the straight line joining two anchors. Walk it, snapping to the nearest word at each step: out comes a road of go-betweens. Pick the two endpoints and see where the trip passes.
The same twelve words, laid out differently — as if another corpus had arranged them. The anchors are the same as above; the road is not. It isn't the endpoints that choose the path, it's the space.
