Write a line you mean. The engine speaks it once, and the incantation is forged into a seal. Phrase as sigil.
The method: the seal is the phrase as spoken, one revolution, clockwise from the top. Vowels ring as formant chords and make the full, round strokes; plosives strike as spikes; sibilants fray the line; the spaces between words stay as breath. The inner curve follows the melody of the vowels, words become the cardinal marks. The same phrase always returns the same seal — unless you let it turn, and then it redraws itself with the month or the day, deterministically. Nothing is random that you did not write.
