A hand holding a pen draws crossed boxes on a storyboard sheet beside crumpled paper balls.

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 sketches, 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 = 307°.
  3. GeometryThe third byte modulo 4 picks analogous, which adds 0°, 35°, 190°.
  4. WobbleThree more bytes shift each by up to ±12° — +2.3°, +8.3°, +8.0° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#b934a5309° at 72% saturation, 73% value#953040350° at 68% saturation, 59% value#368d5a145° at 62% saturation, 55% 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.
