A TV you can break on purpose. The picture is encoded into a real NTSC waveform, damaged the way tape, cable and a tired receiver damage one, then decoded with the mistakes still in. Nothing here draws an artifact — you break something upstream and watch what falls out.
Real-time in the browser, on WebGPU compute shaders.
Requires a WebGPU-enabled browser.
- Every stage of the path, with the hardware fault behind each control: the wiring, the tape and RF, the receiver, the screen.
- Three feedback loops — a camera at the monitor, the mixer patched into itself, and a tape loop with up to four playback heads.
- Two sources, summed dirty or genlocked, with wipes and a chroma keyer.
- Any slider can run on an LFO, random walk, Lorenz attractor or live audio.
- MIDI learn and automap, with soft takeover and clock-locked rates.
- Record to webm or stills, or pop the controls into a second window and point OBS at the picture.
- The whole board fits in a URL, so a link is a patch. Works on a phone.

Running locally adds a YouTube… source the hosted demo doesn't have.

Note: this project is extensively vibecoded. The initial signal-path design was one-shotted by Fable, which nailed the "signal level" idea behind the glitches.
