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 can take any part of an aperiodic tessellation, however large it is, you will not be able to translate it.
You will find them first. Click on the constructions to see the tessellations.
Then you will find non-periodic tiling.
For good clarity, the values of the interior angles are shown on the outside.
