Tessellations have been celebrated for a long time – tessellating patterns can be found in scores of ancient art and interior designs. Their beauty comes from their exactness of repetitiveness, and the fact that there is no space between the interlocking patterns. The earliest known example currently of tessellating patterns being used is from the Sumerians in about 4000 BC, who made snazzy wall designs using repeating patterns made from clay tiles. Tessellating patterns can also be seen in mosaic form in ancient eras, usually used in borders of friezes and to decorate floors of temples for that ‘wow’ factor. Repeating patterns are usually used today for tiled floors, such as in your kitchen or hallway. Tessellations didn’t start to become part of mathematical study until 1891 when crystallographer Yevgraf Fyodorov proved that every possible tiling of a flat surface will feature at least one of seventeen different groups of isometries. It's also Wednesday if that is an easier concept for some
I remember visiting some friends once and they had wallpaper in tessellation patterns of cats similar to this one, https://www.spoonflower.com/fabric/7270546-tesselating-black-white-cats-2-by-eclectic_house drove my eyes crazy
