A model that learned the order of an alphabet — and what it draws past the last letter.
The companion to Capitals and After Nine, aimed at letters instead of digits. Same idea: a net trained to morph a glyph into the next one in its alphabet — B after A, Ψ after Χ — rendered as a slider you can scrub, across Latin, Greek, Cyrillic, and Armenian, upper and lower.
Pick an alphabet and a letter and drag it forward into its successor. The ends are where it gets strange: ask for the letter after Z, or after the last letter of Greek or Armenian, and the sequence runs out. Watch what it draws when there is nothing next.
