A light you keep
your eyes closed for
The torch on the back of your phone pulses. An original score moves with it. A voice carries you through twenty authored worlds, five to thirty minutes at a time, with your eyes shut the whole way.
iPhone, launching soon. 18 and over, after screening. Some answers close the light and are final.
-
The light
Slow pulses through closed eyes, from the torch you already carry. What appears is drawn by your own mind, and it is different every night.
-
The score
An original score for every world, moving as one with the light, from the first breath to the last.
-
The voice
A guide who has been there before. The room, the rope, the stone. Never what you are supposed to feel.
Twenty worlds
Each one built as a piece, not a preset
A working quarry where sound is the work. A stair climbed in the dark. A reef of light a long way under the surface. Every world has its own music, its own voice, and its own way down.
-
The Ascent
first voyage
A stair climbed in the dark, with a stop cut into the middle of it.
Free, always
- Ballast Hold sleep wind-down Under the waterline of a moored ship, where the weight is stacked and nothing is sailing.
- Bell Quarry music immersion A quarry where every block was struck once and listened to before it was cut.
- The Bottle Kiln calm-down A brick kiln two days after the fire, giving its heat back to the floor.
- The Drying Loft sleep wind-down A loft hung with cloth, still air, and a night's work that is only evaporation.
- Hard Ground calm-down A field that went hard in the night, and one gate at the far edge.
- The Icefall deep visuals A glacier breaking over a step, in blocks the size of houses.
- The Lee Wall calm-down A drystone wall on a ridge, with the weather going over the top of it.
- The Lock Chamber calm-down A boat in a stone chamber, and sixty tonnes of water leaving underneath it.
- The Long Weir sleep wind-down Water crossing a cut stone step at the end of a mill leat, hours after the mill stopped.
- The Orrery deep visuals A brass machine the size of a building, still keeping time nobody checks.
- Plumb Line focus reset A cord dropped from a roof so everything built after it has one direction to check against.
- The Reservoir Roof focus reset A concrete lid over a town's water, painted white, with nothing standing on it.
- Salt Halls deep visuals A mine worked out and left standing. The pillars are what nobody took.
- Singing Sand music immersion A dune slip face that sounds, at a pitch somebody measured.
- The Snowline sleep wind-down The line where the snow starts, an hour after the sun has left the rock.
- The Sounding music immersion A weighted line goes over the side and does not find the bottom.
- The Stilling Well focus reset A shaft of seawater cut so waves cannot get in and the level can be read.
-
Undersong Reef
deep visuals
A reef of light a long way under the surface.
Free, always
- The Whispering Gallery music immersion A ledge inside a dome, where a word run round the wall arrives late.
What people describe
Lattices. Slow tunnels of colour. Honeycomb that breathes. No two people are shown quite the same thing.
And some see very little. The first voyage is free, so you can find out. How a voyage works
Worn openly
The numbers nobody else prints
Every light like this runs on limits. Ours are published, and they are the same numbers the app itself enforces.

| Light frequency | 0.5 to 13.0 Hz |
| Never entered, including during ramps | 13.5 to 25.0 Hz |
| Harmonic energy inside that band | at most 0.35 of alternating energy |
| Modulation depth | at most 0.85 of full |
| Torch level | at most 0.6 of the phone's maximum |
| Duty cycle | 0.15 to 0.50 |
| Unbroken flicker | at most 1200.0 seconds |
| Rest between runs of light | at least 1.5 seconds |
| Flicker across one whole voyage | at most 2400.0 seconds |
Who the light is not for, and why, is on the safety page.
