A pseudo-Anosov map is a type of mathematical map that creates intricate patterns out of simple shapes. It works by taking a simple shape, like a triangle or rectangle, and transforming it in ways that generate patterns. The patterns look like they are made up of many tiny pieces all fitting together perfectly, kind of like a jigsaw puzzle. To make a pseudo-Anosov map, you need to select a starting point and an end point, and then you apply a specific rule to each point along the map. This rule creates a pattern that keeps repeating over and over. This makes a very detailed pattern out of a very simple shape!
