ACTIVE. Welcome to my new Google Sites website, rebuilt and reconstructed in July 2024, with its first incarnation being way back in 2003! Web design has moved on. I'm David Bailey from Grimsby, England, with a keen interest in recreational mathematics, of a mostly geometrical nature, and more specifically of all aspects of tessellation. Primarily though, it is overwhelmingly on tessellation, with a strong focus on the Escher-like aspect, which then expanded to include other aspects as well, including strictly mathematical tilings, and 'special case' investigations, such as the Cairo tiling (and pavements in general), houndstooth, cluster puzzles, and parquet deformations. Complementing the Escher-like tessellations are a series of essays on Escher himself. Indeed, the ‘special cases’ are so substantive that any one could be a website in their own right! Other mathematical recreational interests include the Möbius strip, polyhedra, geometric puzzles, and jigsaw puzzles (what is a jigsaw puzzle if not a tessellation?)

The banner? To set the scene, above is a typical example of my Escher-like tessellations, of an aperiodic monotile dog tessellation that got an ‘honourable mention’ in the recent (2023) International Einstein Mad Hat contest. More details are on the ‘Aperiodic Monotile’ page.

Comments, thoughts, queries, commissions etc. are welcomed. Any bona fide email will get a response.
