A person's arm and hand resting on the tufted cushion of an armchair beside their seated leg.

Draws this one again — same subject and the same people, a new palette and a new angle on it, described afresh. It replaces the drawing on this page for everyone, until somebody draws another. Costs the site about eight cents, and a few seconds.

Why these three

Two neighbours reading as one family, and a third opposite them to argue with it.

  1. SeedSHA-256 of what-can-a-prototype-made-of-drawings-never-answer, which is the same every time and different for every piece.
  2. Base hueThe first two bytes as a fraction of 65,535, times 360 = 289°.
  3. GeometryThe third byte modulo 4 picks analogous, which adds 0°, 35°, 190°.
  4. WobbleThree more bytes shift each by up to ±12° — 3.1°, 8.3°, 2.6° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#7c2d93286° at 70% saturation, 58% value#95447f316° at 55% saturation, 58% value#589655116° at 44% saturation, 59% value

Saturation never drops below 72% and value never below 78%, which is what keeps a hue reading as the colour it was chosen to be rather than as a dark. More on how these are made.
