Keith Richardson-Jones Drawing

Don Steward posted this fascinating analysis of a Keith Richardson-Jones drawing in the Tate. I thought it was a good one to adapt and try to generalize. This imagines a square with n points on a side (well, n+1, but n distinct) and numbers then 1, 2, ... 4n. Then it draws a segment from point a to point b, and shifts the endpoints by h1 and h2 respectively, in one direction. Then makes another set starting from c to d, shifted by v1 and v2, in the other direction. Fun effect to play with! But not very intuitive controls - sorry.
