Those beautiful geometric shapes and patterns remind me of why I used to love geometry as a child and young teenager. I was fascinated with the tools - the protracter, compass and set square, and I used to love learning with them. I was very good at maths when I was a child, but as I got into my late teens my maths grades got worse. I'm not sure why. Maybe because the maths got more abstract, although when I first started learning calculus and algebra I enjoyed those subjects too. But in the end I became more interested in art and history.
