Makes me think of what this would look like generalised... drawing with lines and shapes that have their own programmable constraints.<p>See Sutherland&#x27;s Sketchpad demo (1962!) <a href="https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=495nCzxM9PI" rel="nofollow">https:&#x2F;&#x2F;www.youtube.com&#x2F;watch?v=495nCzxM9PI</a><p>Really this is when drawing goes beyond the physical world, and we get to start treating the computer as a co-worker. Snap-to-shape is the first step.
