- A chiral aperiodic monotile, the Spectre.
- An aperiodic monotile: The Hat, a single shape that can only tile the plane non-periodically.
- Lots of Aperiodic Sets of Tiles: If one isn’t enough, how about 25,380 different aperiodic sets? Here are some pix pulled from the paper.
- The trilobite and crab are a simple pair of shapes that enforce the “L” substitution system, though the full proof is not simple at all.
- A description of Aperiodic Hierarchical Tiling.
