Profile

I built a cool browser scene, a shelter window over a dystopian city in the rain. Pull the breaker and a siren tower spins up. The wind-down is super unsettling and I love it.The siren is not a recording. Two port rings make a 5:6 dual tone, 515 and 618 Hz. The horn turns at 4 RPM and everything (loudness, brightness, doppler and stereo position) follows the horn angle you can see on the tower. Rain and thunder are the only recordings.Build it yourself, source is one HTML file and MIT: https://github.com/beeswaxpat/sirenfallHow it works: https://sirenfall.live/how-it-worksPress F for fullscreen, S to save a picture.
