Gummelt Applet - Greg Egan

"Gummelt draws Petra Gummelt's quasiperiodic tiling of the plane with overlapping decagons.
Decagonal tile

This tiling is related to the rhombic Penrose tiling, with a decagon associated with each “fat” rhomb, and the side-matching rules replaced by the requirement that wherever two decagons overlap, the coloured darts they contain are superimposed. Each decagon contains four darts, two of them pointing clockwise and two pointing counter-clockwise, with one pair overlapping."
