Start with something simple. Take four identical equilateral triangles and join them to form a pyramid. This is your building block – a regular tetrahedron, the simplest possible three-dimensional figure.

When you connect five such pyramids by attaching their faces, you will be left with a thin empty space between the first and last: a volumetric angle of 7.356 degrees. It’s too small to fit another piece and too big to be lost in numerical imprecision.

It is a surprising imperfection. You would expect a tetrahedron to behave similarly to its two-dimensional ancestor. When you arrange equilateral triangles, one next to the other like tiles, you can cover two-dimensional space without leaving an empty spot. You may go on forever, covering infinite planes and be sure that the six angles that meet at each point will add up to the perfect 360 degrees.

In three dimensions, it is not like this: you cannot use your building block to fully fill a void. It’s as if the mathematical rules –the ones we tend to idealise for elegance, harmony, and infallibility– broke when you raise complexity.

But mathematical beauty does not reside in perfection. It is through these exceptions that complexity emerges. So keep building, face by face, one block at a time, and embrace the surprising, chaotic aesthetics that appears. A different type of harmony – not based on impeccable proportions, but on unpredictability.
