Six hollow cubes tumbling through space quietly, enjoying their six degrees of freedom. Only a single machine is there to bear witness. It is Sentinel 31, and its mind wanders. Distracted, it recreates the scene, drawing imaginary lines with an imaginary hand.

The original medium of Tumbling Six is the pen plotter. It is entirely vector-based, and can be plotted directly. I use Paper.js to render it on-screen and as SVG, and rely on Three.js for spatial modeling.

To generate and download a plottable SVG file, press `S`. Please be patient; this process can take a while. The SVG can be plotted on an A5 paper. The plottable SVG does not include the light grey sketch lines that appear at the start of the animation. Those look nice on screen, but are too much include on paper.
