**Background:**aperiodic monotile**We watched:**chiral aperiodic monotilemore accessible, a bit silly BUT raised questions for discussion A New Tile in Newtyle - Numberphile - YouTube Finally, a true Aperiodic Monotile! - YouTube more in-depth and answered most of them! Aperiodic Monotile - Mad as a Hat - YouTube Chiral Aperiodic Monotile - Spectre in the Machine - YouTube (this page also has links to the paper on ArXiv and - separately - to a proof that nested hierarchies are not periodic)
