I tried drawing a Koch-like fractal by starting with 48-83-14-48 ^ ^ ^ ^ And then replacing the marked numbers with the whole string to get 4(48-83-14-48)-8(48-83-14-48)-(48-83-14-48)4-(48-83-14-48)8 and iterating from there. Unfortunately the renderer doesn't seem to like it, and in any case a proper Koch curve has lines at all angles, whereas here they must point in one of the eight directions.
