# Kuyu — sources and licences

Everything a visitor sees or hears on this site, and where it came from.

## Fonts (self-hosted, `fonts/`)

| Face | Use | Source | Licence |
|---|---|---|---|
| Anybody (variable: width 50–150, weight 100–900) | display | Google Fonts (`fonts.gstatic.com/s/anybody/v13/`), project: https://github.com/Etcetera-Type-Co/Anybody | SIL Open Font License 1.1 — `fonts/OFL-anybody.txt` |

## Libraries (shared, `../shared/vendor/`)

- Three.js r180 — MIT (`../shared/vendor/three/LICENSE.txt`)
- GSAP 3.13 with ScrollTrigger — GreenSock standard licence, free for this use (`../shared/vendor/gsap-README.md`)
- Lenis 1.3 — MIT (`../shared/vendor/lenis-LICENSE.txt`)

## Images, posters, sound

- **No photographs, no image files and no audio files are used.** Every poster is drawn by code in the visitor's
  browser: a ripple-field model screened as two-ink halftone (`js/print.js` for the 2D canvas, the same model
  as a WebGL shader in `js/wall.js`). The wall texture is procedural (`js/wall.js`).
- Every sound is synthesised live with the WebAudio API (`js/sound.js`): oscillators, filtered noise and a
  generated reverb tail. Nothing is recorded, sampled or AI-generated. The sound never starts by itself.
- `img/mark.svg` (favicon): drawn for this site.

## Facts used

- Fall time of a dropped stone: d = ½·g·t², g = 9.81 m/s² (standard gravity, air resistance ignored).
- Speed of sound in air at 20 °C: about 343 m/s.
- Risograph: a stencil duplicator that prints one colour per drum and pass (general description).
- The "Hicaz" scale in the sketch of track 7 is an equal-tempered approximation; the real makam uses
  intervals outside twelve-tone equal temperament.
