Tessellations-workshop
Tessellation is a system of shapes which are fitted together to cover a plane, without any gaps or overlapping. The word tessellation itself derives from the Greek tessera, which is associated with four, square and tile. Presumably this is an indication of the fact that tiles of this shape are the easiest to interlock. Tessellations are a common feature of decorative art and occur in the natural world all around us.
