How it is built
Points are scattered on a jittered grid matching the canvas aspect ratio, with the frame's edges and corners pinned so the triangles cover everything. The points are triangulated with the Bowyer–Watson Delaunay algorithm. Each triangle takes its colour from the palette at its centroid, along a gradient angle you choose, nudged by low-frequency noise. A small per-facet light term picks out the facets.
Fewer points give bold crystal shapes and more points give a fine mosaic. Turn on edges for a wireframe look. The result is vector, so a 4K low-poly wallpaper is as crisp as a small one.
Reproducible by design
Every image comes from a seed. The address bar holds the generator, the seed, the size and only the settings you changed, so the link redraws the exact same picture on any device. That is useful for picking up where you left off, sending someone a design, or regenerating a file at a bigger size later. See how it works.
