% sierpinski2x2_nonunique2.tiles
%  This early attempt at proofreading improved on sierpinski2x2_nonunique1.tiles
%  by having the information-carrying bond type in even and odd flavors.
%  However, still, each block used a single bond type (unique to that tile) for 
%  cooperative binding, leading to shift-faults along horizontal and vertical lines -- bad!
