Composition by Juxtaposition: A PostScript on Functional Geometry
summary
Claims that Henderson's functional-combinator picture algebra maps cleanly to a concatenative language, implemented here in PostScript concatenative implementation. The code turns the paper's three simple box transforms and combinators into executable arrays, builds recursive reproduction of Square Limit tiles (tea, u, side, corner), and renders the Escher-like tessellation including colored variants. The program runs, produces printable, high‑quality output, and the combinators compose as predicted.
