[NEWS] An alternative proof for an aperiodic monotile is now on arxiv. We prove that Smith hat is tileable and aperiodic. Join work with Prof. Shigeki Akiyama.
スミス帽の「タイル張り可能」「非周期性」の別証明をarxivに公開。秋山茂樹先生との共同研究です。

In Escher’s woodcut “Circle Limit III” the infinite hyperbolic plane (drawn as a finite disk) is tiled with interlocking fish. The tractroid is a surface in Euclidean space with the same geometry as a portion of the hyperbolic plane, so I thought it would be fun to show the fish.
