NON-PERIODIC TESSELLATIONS 
Another extraordinary possibility regarding the tessellations, and never explored by Escher, is that of non-periodic tiles and tessellations.
A periodical tessellation is a set of tiles that pave the plan to infinity by reproducing by translations.
A non-periodic tessellation is a set of tiles that pave the plan to infinity, but without translations.
Its tiles can be either periodic or aperiodic.
Some periodic tiles can pave the plan non-periodically.
A set of aperiodic tiles can only paves the plan non-periodically.
You will find the constructions below. Click to see the tessellations.
For good clarity, the values of the interior angles are shown on the outside.
