Suppose you have a planar polygon, not necessarily convex. The interior face of each edge is a mirror. A candle is lighted at some interior point. The light spreads out, reflects off the mirror edges and spreads further, etc. Is any place inside the polygon completely dark? Rich Schroeppel rcs@la.tis.com
