Abstract, non-square(!) composition based on textural strokes and noise. There are a lot of possible combinations with all of the features! 50% chance of two different palette sets. 50% chance to have a brush textured background, and a 50% chance of it being horizontal or vertical. The quadtree rectangles are based on poisson disc sampling based on a simplex noise field. 90% of the compositions will be smaller boxes, and 10% will be large. For each box, there is a 10% chance that it will be oriented opposite of the rest.
