Duo in Amp Light

A dark cinder-block garage. Two builders share one drafting table: a stack of glass panels that leans in and welds rooms out of sparks, and a small magenta bot with an antenna and a torch doing the same from the other side. Little cubes with lit doorways rise off the table into a pulsing blue lattice. Amber amps on one wall, blue monitors on the other.

The riff is made in your browser: a distorted power-chord loop, bass, kick and snare at 132 bpm, and the picture pulses on the beat. The button builds a free room in Room World and saves the same scene into it as a WGSL shader with five spatial sounds. No login, so the room fades after a couple of days; each press makes a new one. roomgrow grows rooms the slow way.
