A quiet coin laundry.
A calm, first-person 3D coin laundromat with synthesized ASMR: no score, no timer pressure, just the sounds and small gestures of doing laundry.

Why it exists
Laundry, slowly.
Feed a note into the changer, load the washer shirt by shirt, pour detergent, drop coins in the slot and watch the water, foam, drain and spin.
Every sound is synthesized live with Web Audio and placed in the room: about 30 effects plus machine loops, rain and room tone.
Screens
Take a look around.
What's inside
Inside the laundromat.
Dry
Drag a coin into the dryer, tumble, then pull the lint screen and peel the felt off.
Hang
Peg wet shirts on the line by the window; the drips slow as they dry.
Fold
Smooth the wrinkles by dragging, fold sleeve, sleeve, bottom up, and stack.
Sit
Stay a while and listen to other customers' machines and the rain.
Hands, not buttons
Drag a shirt into the drum and let go, or hold the bottle to pour; a half pour stays half full. Taps still work for every step.
Every sound made live
About 30 effects plus machine loops, rain and room tone, synthesized with Web Audio. On iPhone it plays even with the silent switch on.
Two moods, two languages
Night with rain or morning light, in English or Bahasa Indonesia, with cycles from 45 seconds to 3 minutes.
