Scope and license

This tool creates geometric motifs, with no image import, freeform vector editing, animation, CMYK or commercial print profiles. Browser anti-aliasing and system rendering may vary.

The software and included examples are MIT-licensed, including commercial use and redistribution under the license notice. Your own inputs remain yours; simple geometric motifs are not exclusive. Code, design, examples and documentation were made with AI assistance. Runtime generation uses local geometry without AI service calls, external fonts or analytics.
