Spread-Sunk Square Twist Tessellation (SSST)


This tessellation is a very simple variation of the standard square twist which results, nonetheless, in an interesting pattern. Each of the four corners of the central square of the twist is spread-sunk, hence the name. Designed by myself, but since the idea is simple, it may well have been invented by someone else before. Folded from a sheet of thin mulberry paper with a golden leaf motif.
