Examples
Two small apps, runnable in the page.
The Wardrobe
A dream as a scene: a man and a wardrobe, each with intents (how big his hat is, where he stands, how far the door opens). One sentence moves the scene; a sentence nothing reads is handed to a model, which learns a new kind.
Slides on every screen
One slide shown on several screens at once. A row of pictures is arranged differently as screens get narrower; choosing an arrangement on one screen carries to the screens narrower than it.
Status
Both run on recorded model answers, so they need no key. They arrive with the library.
