TITLE: Pulsar Ridges FILE: 079-pulsar-ridges.html === PROMPT (exact prompt used) === Build "Pulsar Ridges", an animated, original piece in the spirit of classic stacked ridge-line plots. Black background (#000) with ~60 stacked white lines (#f5f5f5) drawn on canvas with occlusion (each line filled black beneath so nearer lines hide farther ones); each profile comes from layered noise plus a central peak region and animates continuously, so the ridges roll like a landscape of signals. Interaction: the pointer position becomes the source of the peaks (ridges swell toward the cursor); clicking switches data modes: "Pulsar" (sharp central peaks), "Terrain" (mountain noise), "Audio" (a built-in synthesized drone analysed with an AnalyserNode drives the lines, after a gesture) and "Heartbeat" (ECG-like spikes). Settings: line count, amplitude, speed, colour mode (white, amber, spectrum gradient). Minimal typography: a small, uppercase, widely tracked monospace caption at the bottom like an album credit.
