This is a live coding session based on a classic 1982 paper by Peter Henderson. We'll see that framing a problem in the right way enables us to solve it in interesting and elegant ways. The problem in this case is the transformation and combination of pictures to form new and more complex pictures. If we think of an picture not as a collection of colored pixels but rather as a function from a bounding rectangle to a rendering, we can define simple yet powerful picture combinators that allow us accomplish our task with ease and elegance. As a demonstration, we'll use our combinators to make a replica of Henderson's replica of Escher's Square Limit woodcutting.
