A rule-based composition tool for geometric works on a modular grid. Each cell holds one of four module types — stripe pattern, direction, and color pair. The composition emerges from the system, not from gesture. The name blends Raster (grid) and Kompositor — the instrument that composes — in the spirit of Concrete Art (Max Bill, Karl Gerstner): form that follows its own logic.
Use the module strip (tune) to define up to four module types, then fill the grid by clicking cells or using the keyboard.
