Drawn in the browser

This generator does not send you an image. The server sends a short description of one — the parameters below, plus a 32-byte key — and the drawing is done here, from the same byte stream the server would have used. That needs JavaScript, so with it switched off there is nothing to show.

The description itself is still public: /api/v1/g/patterns.worley returns it, and the maths is in resources/js.

Class C · Observational cached

A magnitude 4.3 earthquake, 13 km NW of Cepitá, Colombia, 153.8 km down — 49 minutes ago.

Carries only tens of bits of genuine surprise. Always mixed with the OS CSPRNG.

source: USGS Seismic Feed
observed: 2026-09-13T17:55:25+00:00
latency: 0ms
mixed with: csprng — always

The token is the seed, so this link recomputes the result rather than looking it up. No database, and it works for as long as v1 does.

Feature points are scattered one per grid cell, so this is both the cell count and the point count.

Distance kept

Distance metric

Minkowski p

0.4 8

Only used by the Minkowski metric. p=1 is Manhattan, p=2 is Euclidean, and large p approaches Chebyshev.

Scatter

0 1

How far a point may stray from its cell centre. At 0 the grid is perfectly regular and you get a tiling.

Banding

Quantise into flat bands instead of a smooth gradient.

Entropy source

Picking a source changes the story on the receipt, never the quality: anything below class A is mixed with the OS CSPRNG before it reaches you. This result actually came from USGS Seismic Feed.

Re-render keeps this token. Generate replaces it. That is the whole idea.

Burned into the corner before the file is written, so the image keeps its provenance wherever it ends up:

This page and /api/v1/g/patterns.worley run the same code. There is no private endpoint.
