Your name becomes a number, and the number paints the picture: one of 8 styles, a five-colour palette and every cell in the canvas. The same name always paints the same painting, so a link to yours shows everyone exactly what you got.

Live engine loads in a moment (301 KB). This is a still from it.
Your painting
The style comes from the seed: colour field, grid, drip, landscape, nested squares, portrait, target or pop quadrants.
How to use it: type a name (yours, your dog's, your startup's). The painting changes as you type. Surprise me paints from a random number instead. Download PNG saves it with its plaque.
How it works
- It is the real engine. Proof Engine is the Rust renderer O'BLOCK ships with. For the web I compiled it to WebAssembly (301 KB gzipped) and swapped its desktop OpenGL window for a WebGL2 canvas. Same glyph-particle renderer, same HDR bloom and colour grade as the game.
- Name to number. Your name, trimmed and lower-cased, goes through a 64-bit hash (FNV-1a, then mixed), so there are about 18 quintillion possible paintings and changing one letter changes everything.
- Number to painting. The number picks the style, the frame, five colours and where every split, drip or ring goes. Then each cell is coloured with a little grain, the way O'BLOCK paints the art in your crib.
- Styles borrow from the canon, never its pictures: colour fields, grids, drips, landscapes, nested squares, portraits, targets and pop quadrants.
- Nothing leaves your device. Everything is computed in your browser tab. No account, no upload, no tracking of what you make.
