The Delft Wall

Blue-and-white tiles go up one at a time. Each tile's edges carry the ends of the painted vines and channels, and every tile must agree with the edges of its neighbours. The wall is built by wave-function collapse. Each empty slot keeps a list of the tiles that could still go there, the slot with the fewest options is painted next, and its neighbours drop the tiles that no longer fit. Continuous vines and canals emerge with no plan, with a diatom, a tardigrade or a windmill in the corners. Each painted tile is a reservation on the ledger. Tap a tile to knock it out, and the wall repairs itself around the gap.

LIT: Delftware is Dutch tin-glazed earthenware (17th c. onward), painted in cobalt blue and inspired by Chinese porcelain. Wave-function collapse is a constraint-propagation algorithm (Gumin, 2016). ANALOGY: the "wave function" is only a list of candidate tiles, not quantum mechanics.

Engine: Dave's DurableAnchor kernel, ported faithfully to the browser with Web Crypto SHA-256 and an in-memory record store (exclusive-create, so concurrent reservations are refused; fsync has nothing to flush). The ledger starts empty on each load. Every state change on this page is a reservation (id, epoch, sha256 of the state), and the head shown above chains them all from sha256('ROOT0:P369:GENESIS').
