Minipix Subdivison Renderer

I've written a new renderer for Minipix: Subdivision. The renderer begins with the whole image and asks: "How can I break this into pieces?" It draws an imaginary line—horizontal or vertical, somewhere random—splitting the image in two. Then it looks at each piece and asks again: "Should I break this further?" Sometimes it does, sometimes it stops. This continues, each region potentially subdividing into smaller regions, until the image is a mosaic of fragments—some large, some small, following no particular logic. Then comes the transformation, each fragment is randomly flipped, horizontally or vertically to create a mirroring reflect across the irregular grid. What emerges is recognizable yet alien, its continuity broken into discontinuous reflections of itself.
