June 3, 2019 | @aschinchon

Agarrada a mis costillas le cuelgan las piernas (Godzilla, Leiva) Penrose tilings are amazing. Apart of the inner beauty of tesselations, they have two interesting properties: they are non-periodic (they lack any translational symmetry) and self-similar (any finite region appears an infinite number of times in the tiling). Both characteristics ...
