Night Train LIVE
Night Train
Ambient Audiovisual  ·  Generative Soundscape  ·  Sleep & Focus
A parallax night-train journey through dark countryside, built entirely in the browser using HTML5 Canvas and the Web Audio API. No loops, no samples — everything synthesised live. Watch hills pass, farm lights drift by, the occasional platform or bridge. Hear rhythmic track clatter on jointed rail, carriage creak, a distant horn, rain against the glass.
Runs indefinitely. Adjust speed, interior acoustics, weather intensity, and sound effect rates. Sleep mode strips it back to background rumble and track rhythm — ideal for overnight sessions.
