Tile

Found this generator for aperiodic Penrose tile, makes a pretty picture.  A JSL implementation should use recursive function calls to make it faster; expanding the string of symbols gets really slow for a really big tiling.  Using transparency shows the generator code makes the same lines more than once.  There is 5-way symmetry around the center.  This is an 8-level deep recursion.
