Been looking for profound simplifications. One way to simplify a scene is to draw it from memory. Another way is to draw very small: the smaller the space is, the less room there is for detail. Hence a small drawing or a remembered scene provides a grand strategy for getting to the core of things.
Naturally enough, the little drawing is a form of invention also. For how many ways can you remember a thing? How many ways can you break it down into its simple elements? It turns out that there are many ways.
