Slowly-forming triangles change over time.

Features:

- Palettes are chosen from a curated range. The most common size has six colours, but there is a chance of three, seven or eight.

- Triangle orientation takes two forms. These are subtly blended over time.

- Spacing and grid size are chosen from weighted values.

This piece is designed for display and changes slowly over time. Resizing the window will produce the same pattern, but progress so far will be cleared and the formation process will start again. This is because the pattern is produced by layering over time.
