Deconstruction of simple 3D volumes.

- Pen/ink style rendering.
- p5/JS, no WebGl.
- This is CPU heavy and comes with a preloader.
- Drawing is done in background, if you switch tabs it pauses.
- Single HTML can be right click saved - runs anywhere. No assets are loaded.
- 'd' downloads current render
- '2' reloads at x2 pixel density for printing (then 'd' to save)
