Penrose is a neat name for this. At first I thought it was not a great choice because of other associated concepts. Then I noticed pen=write, rose=draw. Maybe not intentional, but cute.

It's an infinite plane of tiles, procedurally generated, that never repeats no matter how far you go.
The discovery of Penrose tilings is partially tangled up with the discovery of quasicrystals, where researchers found minerals with 5-fold and 10-fold symmetry that ought to have been mathematically impossible to exist. Turns out that the Crystallographic Restriction Theorem has an important caveat that people neglected up until the 1980s: it assumes that you have to have translational symmetry, which Penrose tilings do not.
The notation feels c like.
Maybe it could be interesting for knots and complicated algebraic geometry?
