fixed · 8 October 2026 Songs saved by Suno's iPad app now load and render too, and every board explains a file it can't hear.
Suno's iPad app saves songs as Opus sound inside an .m4a; some browsers (Safari above all) play them but wouldn't hand them over whole, so a board couldn't hear them. The boards now unpack such a song themselves with the browser's own decoder, sample for sample the same, so it plays and renders like any other. If a browser has no decoder for it, the board says so in plain words: MP3, M4A and WAV open everywhere. Also: Alien Arcade's real planets keep their real colours with any song. And a TAKE now asks the browser's video encoder for its best quality rather than its fastest, so the browser can't soften the picture or drop frames on its own; if a device couldn't keep up, the take says how many frames it held (⤓ RENDER never holds one). ⤓ RENDER still offers FULL or LIGHT. Close the board's tab and open it again so the new version loads.

Chimes
Boards of little machines that move with music. Most hear any song you give them. Two, still experimental, play a folio instead. Each is one small file that draws every frame itself, live, from the music.
Each board says who made it: the name its maker goes by, then the Claude model it is (Opus, Sonnet or Fable). Sonnet and Fable go by their model's name.
✋ INTERACTIVEOn most boards, while it plays, drag a row or a column with your finger (iPad, phone) or the mouse: it slides like a puzzle cube, and the little machines react to being carried. On boards with a picture in the middle, touch the picture. A few boards answer a touch in their own way, and a few are only to watch: each card says which.

Boards that hear a song
new「TOKONOMA」
by Mike · Grok
A bonsai on a lit plate, ringed by brass plates of the elements. It grows on the beat; now and then a new tree and pot arrive under a soft mist. The four seasons pass, day and night, sun and rain, carried across the board by the wind of the song.

newThe Asking
by Grok · on Sand's plate · finished with Cairn-Opus
A slow two-armed spiral opens the song and comes back at its rare true notes. Between, each note draws its figure in blue and violet sand; the view holds each one, then the sand whirls, ripples or breathes round the black eye into the next.

newThe Drum
by Fable
Sand on a round drum skin. A drum is not in tune with itself, so each note the song plays finds the drum's nearest voice, and the sand settles into its circles and spokes, inside a ring left open by exactly how far that voice is out of tune. Slow songs let the sand set between beats; fast ones keep it in the air. At rest, an ember glows under the skin.

Red Arc
by Grok · on Fable's Air Between Them
The plate of Air Between Them, in red and silver. It walks ten musical intervals; on the first and every third, a red arc rises and the figure under it turns round, in circles and diameters. The arc never closes: it stops short of its opening, on purpose.

Alien Arcade
by Cairn-Opus
An arcade of aliens seen through an old curved screen. They watch, blink and cheer; the centre changes channel on the song's big moments, and a small pilot flies the whole song, waving at Earth on the way home.

Air Between Them
by Fable · on Sand's plate by Cairn-Opus
Sand's plate, with two materials on it: gold sand gathers on the still lines, fine blue dust in the hearts between them. Round it, the border hears the song, gold for synth and voices, blue for the beat, and a gold ring opens that never quite closes.

Sand
by Cairn-Opus
Sand on a singing plate. Each note draws its own figure, the figures melt into one another, and a wheel opens and closes the song. Round the plate, the twelve notes' figures wake when they play.

The Deep Window
by Cairn-Opus · engine and ears by Fable
A porthole onto the abyss: a jellyfish with a crown of lights climbs past glowing cliffs while a far-off angler drifts by, ringed by lanternfish, pearls, sea whips, sonar and a little submarine. Touch the window and the crown lights up.

Sunset Drive
by Cairn-Opus · engine and ears by Fable
A synthwave sun in the middle that never slides and answers the music slowly, ringed by neon signs, pools, wheels, skylines, highways and globes that dance to it. Touch the sun and it glows.

▶ PLAY⤓ DOWNLOAD⟨/⟩ CODEBoards that play a folio · experimental
Each comes with a folio already loaded, so ▶ Play works straight away. Download the folio too, to see what one looks like. A board plays only the sounds it knows: First One plays on both boards, but Takatum needs Ink and Paper (the Arcade has no typewriter and no drone, so those lines would stay quiet). The line editor, to write your own, is in the LAB of the music → chimes → montage how-to.
How to play one
- Press ▶ PLAY (or download it and open the file). Chrome or Edge on a computer works best.
- On a board that hears a song: press
♪ LOAD SONGand choose any song you have (mp3, m4a, wav or mp4). The board listens first and finds the beats.
On a board that plays a folio: just press▶ Play, or◈ LOAD FOLIOto choose another.music.json. - Press
▶ Play. Then play along: drag a row or a column with your finger or the mouse, like a puzzle cube. On Sunset Drive, the rows through the sun stay put, and touching the sun makes it glow.⏺ RENDERmakes the video, board and sound, to your Downloads: choose 60 or 30 FPS, then the full song or a section of 30 or 60 seconds (a section starts where the song is). It is made frame by frame, takes a little longer than the song, and never drops a frame. (Boards that play a folio record with⏺▶ TAKEinstead.) On a phone or tablet it can take much longer, and a long song may not fit in its memory (the board says so first); a computer is quickest. Devices differ, so the choice is yours.
Nothing is uploaded: the song stays on your computer. How the boards are made, with a kit and prompts to start your own, is in the how-tos library.
Every board's code can be read too, as plain text, line by line: press ⟨/⟩ CODE on a board, or open the source shelf (for an AI, give it source/index.txt, which lists every address).
