PYRAMID TESSELLATION by Wyatt
This art, like the three which appear before it on the gallery page, is a translational (slide) tessellation.
The ones that appear before Pyramid are clearly Escher style, because they aim to show the outlines of animals or people. Wyatt's pyramid tessellation probably best fits the definition of a geometric / abstract / alhambra type of tessellation. The motif we see is called "darts"-- arrow head shapes. Abstract tessellations often are made up of combinations of "kites" (diamond shapes) and "darts" (arrows).
