Shapes that tessellate fit together with no gaps or overlaps Escher (1898 - 1972) was a Dutch graphical artist most famous for his impossible structures and mathematical tessellations. I did this excercise with my Key Stage 2 Art Club tonight. Here's a 'How to' sheet for you to try. Follow these instructions for a simple tessellating pattern and this could be your first step towards something as amazing as Escher! I'm happy for you to print off the JPEG for your private use.
