In this exhibit, you can draw coloured lines with your finger, which are then multiplied according to a selected symmetry rule. But where do these symmetries come from? And what is the exhibit all about? This is the question we want to explore in this advanced text.
You encounter symmetrical objects and patterns every day. A parquet floor is usually laid in a periodic pattern. The tiles in your bathroom on the wall as well. But what are the fundamentally different ways of filling a plane with a periodic pattern? This question is to be answered vividly by the present exhibit “Ornament“. The seventeen different choices you have are, in a sense, “all” there are.
