A real, scannable QR assembling module by module while a laser line sweeps down the tile.
The ask a camera answers rather than a tap, for the end of a video where the link cannot be a link. The code is generated from whatever address you put in the field — modules edge to edge, error correction at the level that survives being filmed off a screen — so the thing on screen is the thing that scans. Keep the destination short and worth the effort of picking up a phone; a QR pointing at a home page is a QR nobody scans twice.
