## Captures

The captures on the shelf are Splashery's own files, served at [splashery-assets](https://ryanjosephkamp.github.io/splashery-assets/) (`assets/toys/<id>/`: the SOG file, its lighter copy for phones, any other looks, and the shelf picture). Lite ships eight of them itself (the grape, the strawberry, the raspberry, the blackberry, the blueberry, the cinnamon star cookie, the tomatoes, and the carder bumblebee, copied unchanged), and this site its own wind-up robot (labs) and five CC BY 4.0 captures from SuperSplat that it edited itself (labs: the Ship model, the Typewriter, the Vanadinite, the Rangefinder camera, and the Cherry tree, made by `tools/capture-edit.mjs` from the recipes in `tools/capture-edit.json`, with their light files made by `tools/light-file.mjs`); the rest come from that site (`src/splashery/CAPTURES.json`). Each is used under its own license below, with the changes Splashery made to it; the shelf pictures are rendered from the captures. For 22 of them this site keeps its own light file, `assets/toys/<id>/<id>-thin.sog` (`tools/light-file.mjs`): 100,000 of the full file's splats, picked and copied unchanged, under the capture's own license. The page shows each capture's credit under the shelf. 3 of them (Dog plush, Desk globe, Cherry blossom (photo)) are licensed for non-commercial use only, and the page says so beside their credit. Since October 23, 2026 they are not shown, and neither is the Stannern meteorite (CC BY-NC 4.0, credited in `src/splashery/CREDITS.md`): the four are off the shelf, search, Surprise me, and the New shelf, their files and credits stay, and a link to one still opens it with its credit (`?old=nc-toys` lists them again). Labs captures show on the shelf with labs on. The five SuperSplat captures' license, "CC BY 4.0", was checked on each live page on October 24, 2026, when their files were downloaded. Eight more CC BY 4.0 SuperSplat captures were edited the same way that day (labs: the Space capsule, the Antique car, the Mail biplane, the Model touring car, the Classic sports car, the Track car, Cochem Castle, and Smederevo Fortress), their license checked on each live page when their files were downloaded; their SOG and light files are served from Cloudflare R2 (https://assets.splashery.app/, in `toys/<id>/`), not the repo, and only their shelf pictures are in `assets/toys/<id>/`. Since the evening of October 24, 2026 their files and the five's are made without the edits that hid a mark (a maker's badge, name, or logo, a model name, a license plate, the Track car's driver's face, and the Vanadinite's coin), so each shows as captured; the first files, with those marks hidden, are served with `?old=redactions`, and [the redaction ledger](docs/licenses/redactions.csv) lists every mark hidden on any toy, what it hid, and what a sale might need. The five's SOG and light files moved to R2 then too. The Perseverance rover (labs) was edited the same way that day, from a CC BY 4.0 synthetic scene that its author made in Blender from NASA's 3D models of the rover, Ingenuity, and a sample tube ([NASA's 3D resources](https://science.nasa.gov/3d-resources/mars-2020-perseverance-rover/), NASA/JPL); its license was checked on the live page when its files were downloaded, its files are served from R2 like the eight's, and it shows NASA's insignia, JPL's logo, and the Mars 2020 mission logo as captured (NASA's [images and media guidelines](https://www.nasa.gov/nasa-brand-center/images-and-media/) keep its insignia out of the public domain and rule out implying its endorsement: its first files, with the three painted out, are served with `?old=redactions`).

## Code

- **The renderer, the SOG reader, the camera, the sort, and the pick** come from the Splashery
  pitch page (`splashery-pitch/` in Ryan Kamp's portfolio repository, which is private; his
  published [portfolio sites](https://ryanjosephkamp.github.io/portfolios/) are public), MIT, by
  Ryan Kamp, cut down for a playground. The SOG reader follows
  [@playcanvas/splat-transform](https://github.com/playcanvas/splat-transform)'s own reader.
- **The WebP decoder** (`src/vendor/webp/`, `webp.mjs` and `webp.wasm`) is PlayCanvas's,
  from @playcanvas/splat-transform, MIT, copyright PlayCanvas Ltd.; its license is beside it.
- The quad's reach (2.83 standard deviations), the 2-pixel floor, and the minor axis's floor follow
  the [PlayCanvas engine](https://github.com/playcanvas/engine)'s splat shader (MIT), so the two draw
  alike.

## The Collapsing Vortex

The Splash is a schematic made in the page, from no outside picture or code. Its flow follows the
description of the leading flow in *Finite Time Blowup for Navier–Stokes*, a preprint by OpenAI
(September 2026): https://cdn.openai.com/pdf/32d9f210-8b73-45e0-91bc-82a30aef8a9a/navier-stokes.pdf.
Its text mentions earlier work on forced blowup that the paper cites: Diego Córdoba and Luis
Martínez-Zoroa, *Blow-up for the incompressible 3D-Euler equations with uniform C^(1,1/2−ϵ) ∩ L²
force*: https://arxiv.org/abs/2309.08495.

## The Black Hole Merger

The Splash is a schematic made in the page, from no outside picture or code. Its black holes, their
horizons' areas, and the final black hole's ringing follow the numbers in *GW250114: Testing
Hawking's Area Law and the Kerr Nature of Black Holes*, by the LIGO Scientific Collaboration, the
Virgo Collaboration, and the KAGRA Collaboration (Physical Review Letters 135, 111403, 2025;
CC BY 4.0): https://doi.org/10.1103/kw5g-d732. The ringing's frequency and decay use the Kerr fits in
Emanuele Berti, Vitor Cardoso, and Clifford M. Will, *On gravitational-wave spectroscopy of massive
black holes with the space interferometer LISA* (Physical Review D 73, 064030, 2006):
https://arxiv.org/abs/gr-qc/0512160. Its text cites Stephen W. Hawking, *Gravitational Radiation from
Colliding Black Holes* (Physical Review Letters 26, 1344, 1971):

## Sound

The tap sounds are Splashery's own: its sound engine, its library of synthesized voices, and each
toy's tap sound (`vendor/splashery/src/sound.js`, `voices.js`, and `toy-sounds.js`, MIT, copied
unchanged; `vendor/splashery/VENDOR.json` records each file's commit and SHA-256). Four of the eight
toys' sounds use recorded samples, from Splashery's `assets/sounds/`, all under
[CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/):

| File | Toys | Source | Author |

This site's own recorded hits (`src/sound-samples.js`; `?old=kenney` plays the synthesized ones)
are in `assets/sounds/`: six files from [Impact Sounds 1.0](https://kenney.nl/assets/impact-sounds)
by Kenney, under [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) (checked on the live
page and in the pack's `License.txt`, October 21, 2026). `tools/kenney-samples.mjs` makes each from
the pack's file: mixed to mono, cut where it falls silent with a 10 ms fade, its peak set to −1
dBFS, and saved as a 64 kbps MP3.

## Listening for notes

A piano toy's song panel hears a recording's notes with one of two models, both run on the device
(lane Audio piano, `src/splashery/transcribe/`; the license texts are beside each model):

- **Piano:** the note model of Qiuqiang Kong, Bochen Li, Xuchen Song, Yuan Wan, and Yuxuan Wang,
  "High-resolution Piano Transcription with Pedals by Regressing Onset and Offset Times" (2021),
  from [Qiuqiang Kong's checkpoint](https://zenodo.org/records/4034264) (ByteDance), under
  [CC BY 4.0](https://creativecommons.org/licenses/by/4.0/). Changed: the note model alone,
  exported to ONNX at half size (`tools/piano-model-export.py`).
- **Any instrument:** [Basic Pitch](https://github.com/spotify/basic-pitch) by Spotify (Bittner et
  al., 2022), Apache License 2.0, unchanged.

## The piano songs in Sound in a Box

The longer songs on Sound in a Box's list, beside its tunes, are the built-in songs of the Grand
Piano, the Upright Piano, the Harpsichord, and the Electronic Keyboard
(`src/splashery/packs/pianos.js`), played the way each of those Splashes plays them: a song's notes
and pedal through that keyboard's voice, made into a sound file in the page when the song is chosen.
Every piece is in the public domain (each composer died more than 70 years ago, or the tune is
traditional). The notes are written out in `pianos.js` from the scores and checked against the
Mutopia Project's public-domain editions, where it has one; no recording of any piece is used.
Mutopia's page for each edition says Public Domain (read on October 26, 2026). The Grand Piano's
notes are recorded piano notes by TEDAgame under
[CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) (credited in
`src/splashery/CREDITS.md`); the other voices are made in the page by `src/splashery/voices.js`
(MIT).

| Song | Composer | Played by | Mutopia's edition (Public Domain) |
| --- | --- | --- | --- |
| Gymnopédie No. 1 | Erik Satie (1866–1925), 1888 | Grand Piano | [Dover Edition](https://www.mutopiaproject.org/cgibin/piece-info.cgi?id=37) |

| Minuet in G | From the Notebook for Anna Magdalena Bach, 1725 (BWV Anh. 114, now credited to Christian Petzold) | Harpsichord | [Bach-Gesellschaft](https://www.mutopiaproject.org/cgibin/piece-info.cgi?id=75) |
| Twinkle, Twinkle, Little Star | French folk tune, 1761 | Electronic Keyboard | none for the tune alone (Mutopia has [Mozart's variations on it](https://www.mutopiaproject.org/cgibin/piece-info.cgi?id=2236), also Public Domain) |
| Frère Jacques | French round, 1700s | Electronic Keyboard | none (a traditional round) |

## The recordings in the sample song lists

Song landscape opens on, and Sound in a Box and Song landscape both offer, two recordings
(`src/ui/song-samples.js`), beside the tunes and the piano songs above.

| Song | Made by | Source | License | Changes |
| --- | --- | --- | --- | --- |
| Clair de lune, from the Suite bergamasque (Claude Debussy, 1905; public domain) | This site: the Grand Piano's Clair de lune above, the public-domain score played through the Grand Piano's recorded notes by TEDAgame | `assets/songs/clair-de-lune-piano.m4a`; the score as in the table above, the notes from [88 piano keys, long reverb](https://freesound.org/people/TEDAgame/packs/25405/) | [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) | Rendered ahead of time by the page's own code and encoded as AAC-LC at 48 kbps, mono, in an `.m4a` (251 KB, 44.9 s), with `tools/song-recording.mjs`; the sound is otherwise unchanged. |
| Sample tune | Splashery (our own tune) | `assets/toys/song-landscape/sample.wav`, served by splashery-assets | [CC0 1.0](https://creativecommons.org/publicdomain/zero/1.0/) | none |

The score is in the public domain (its composer died in 1918 and it was published in 1905; Mutopia's
edition says Public Domain, read on October 26, 2026), and the notes are CC0, so the sound file
asks for no credit; Song landscape and Sound in a Box show one beside the song anyway. The file is
this site's own, because splashery-assets isn't written to from here. No recording of the piece by a
pianist is used.

## Your book's manual and its cover picture

`manual/tinkerers-manual-ad72e927bef5ea54.pdf` is the Tinkerer's Manual, Your book's sample, copied
unchanged from classic's `382b065` (its name carries the start of its SHA-256). It came from the
classic site until October 23, 2026; the copied files' own site, which took over then, has no
`manual/`, and the classic site's address for it now answers 404, so it is kept here (October 24,
2026). `assets/toys/your-book/manual-cover.webp` is its first page, drawn at 1,024 × 1,325
pixels by PDF.js and saved as a WebP by `tools/manual-cover.mjs`. Their credit and license are the
manual's: Splashery's own work, credited in Splashery's `CREDITS.md` as Your book's sample, under the
MIT license (`LICENSE`). Your book shows the picture on its cover while the manual downloads.

## Share links

Links are in Splashery's own scene format, read and written with its `codec.js` (MIT, copied
unchanged into `vendor/splashery/src/`).

## Fonts on the Pitch page

`site/about/splashery/` sets its headlines in **Instrument Serif** (The Instrument Serif Project
Authors, https://github.com/Instrument/instrument-serif) and its labels in **JetBrains Mono** (The
JetBrains Mono Project Authors, https://github.com/JetBrains/JetBrainsMono), both under the
[SIL Open Font License 1.1](https://openfontlicense.org/), taken from Google Fonts' repository on
October 14, 2026 and subset for the page (`LICENSES.md`). No other page loads them. The page also
shows the grape (Dany Bittel, CC BY 4.0), the photo "Forest Away Path" by Seaq68 (CC0 1.0), and the
walnut CT scan (Der Sarkissian et al., CWI, CC BY 4.0), each with its credit beside it.

## The Night sky's own assets

The Night sky (labs) draws its sky, stars, and Moon from three files in `assets/toys/night-sky/`,
made by `tools/night-sky-assets.py` (`?old=night-sky` draws the splat sky without them). Its other
data (the brighter stars, the constellation lines, the planets' formulas) comes from Splashery and is
credited in `src/splashery/CREDITS.md` and beside the toy; these are credited beside the toy too.
