[ Take 3 --- with apologies to Rich! ] After GoogleDocs rehashed their interface again --- which it admittedly needed --- I can't upload there any more. So I've attached a GIF graphic, which I hope will sneak under the 40Kb limit set by the math-fun server. An efficient algorithm (combinatorial, rather than generic polygon-filling) to fill the original snowflake curve required some thought on my part, although in the end it isn't very difficult. The natural tiles are rhombs, rather than RWG's hexagons [hexflo.png]. However, I haven't yet figured out a neat way to use them directly, rather than split into two triangles. The two regions are simply connected, unsurprisingly though not immediately obviously --- take the ends of a finite segment of curve and pull? Rather grotty Maple code & larger pics available on request. Fred Lunnon
