“The Infinite Pattern that Never Repeats”, a presentation by Paul Steinhardt on the problem of “tiling the plane” to infinity” (as in flooring), on the Versatium channel. Indeed, what a geometry lesson.
The concept is called “Penrose tiling”, which I will defer to Wikipedia for explanation. A related problem is how “quasi crystals” form in nature.

One can certainly imagine board or computer games based on this mathematics. Kadi Runnels explains how tiling can he used to explain the speed of light and relativity here.
