Man seen from behind at a desk facing a monitor and a laptop showing a face, surrounded by swirls.

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

The opposition backed off by 30 degrees either side, which keeps the contrast without the vibration.

  1. SeedSHA-256 of who-verifies-what-the-agents-built, 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 = 112°.
  3. GeometryThe third byte modulo 4 picks split, which adds 0°, 150°, 210°.
  4. WobbleThree more bytes shift each by up to ±12° — 11.5°, +6.3°, 9.4° — so two pieces that draw the same geometry are still not the same shape on the wheel.
  5. Result#549d2f100° at 70% saturation, 62% value#8242cd268° at 68% saturation, 80% value#962e81312° at 69% 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.
