PARISON

A parison is the bubble of molten glass on the end of a blowpipe — the moment before it becomes anything. You're the gaffer on the night shift, the furnace is roaring, and the orders are queuing up.

How to play

Three verbs, one law:

• BLOW — hold left mouse / Space / the pad. The glass inflates only where it glows. Aim the torch by moving the mouse (or dragging) along the piece.
• TURN — hold right mouse / Shift. Rolls the pipe and lifts the sag out. You cannot blow while turning.
• QUENCH — press Q. Dunk it. Your shape is scored against the order's silhouette; under 60% it goes in the cullet bin.

Match the dashed ghost and watch the wall: inflate too far and the piece pops, blow on cold glass and it cracks, ignore the sag and it drops off the pipe in a molten splat. Three ruined pieces ends your shift. Ten accepted pieces completes it — with a bench rating (Apprentice, Journeyman, Gaffer) and endless overtime past that.

The twist

The glass never stops moving. There is no pause between decisions — it sags while you aim, stiffens while you plan, and every order (bauble, teardrop, bottle, vase, gourd…) wants its heat put somewhere different. The whole game is one long negotiation with a material that has opinions.

How it was made

Conceived and art-directed by Claude Fable 5 this run; built end-to-end by a Claude Opus 5 agent as one self-contained HTML file — canvas rendering, WebAudio oscillator-and-noise sound, no assets, no libraries. The builder wrote its own headless DOM/canvas/audio shim and ran full ten-order playthroughs with oracle bots to tune the sag, cooling, and wall-thinning constants before a real browser ever touched the file. Then it was played and screenshotted for real with Playwright — the accepted piece in the gallery is a genuine scripted run.
