Credits and licences

Last updated 24 September 2026

Ebru Studio is made by Meriç Dağlı. Everything you see and hear is made for it, or used under a licence that allows it, or old enough to belong to everyone. Here’s all of it.

The craft

Ebru is a living tradition, and the studio stands on it: the classical patterns (battal, gelgit, taraklı, şal, bülbül yuvası, hatip), the flowers of Necmeddin Okyay and Mustafa Düzgünman, the akkâse of the old masters, and the marbling of Japan (suminagashi), Persia (abri), the Deccan and Europe. The demos follow their methods; none of them copies a particular sheet.

The water and its mathematics

The way paint moves on the tray follows the mathematics of marbling worked out by Aubrey Jaffer and his colleagues (Shufang Lu, Aubrey Jaffer and others, “Mathematical Marbling”, IEEE Computer Graphics and Applications, 2012), which also treats combs and pins as exact movements of the water. Amanda Ghassaei’s Digital Marbling showed how beautiful this can be on a screen, and was a guide for this studio. The realistic tray borrows ideas from Evan Wallace’s WebGL Water and Aurélien’s Clearwater (both MIT licensed) for its ripples, and from Adrien Bousseau and colleagues’ interactive watercolour (2006) for the grain of the pigment.

Music

All music and sound is synthesized live in your browser: no recordings or samples. Its scales and forms come from traditions that belong to everyone: Turkish makam and usul, Japanese pentatonic modes, Indian ragas, Javanese and Balinese pelog and slendro, and European harmony. The Turkish tunes it sometimes plays are transcribed from Rauf Yekta Bey’s “La musique turque” in the Encyclopédie de la musique (Paris, 1922), which is in the public domain: his own short pieces in each makam, and a yürük semai by Dede Efendi as he printed it.

Pictures in the demos

Some demos are homages, made in ink on water, to works that are in the public domain: Vincent van Gogh’s The Starry Night (1889), Katsushika Hokusai’s The Great Wave off Kanagawa (about 1831), Claude Monet’s water lilies, Gustav Klimt’s The Tree of Life (1905 to 1909) and Wassily Kandinsky’s Several Circles (1926). Others are in the spirit of a style (op art, De Stijl, early abstract painting) without following any particular work. The science demos after G. I. Taylor’s reversibility experiment (1967), Hassan Aref’s blinking vortex (1984) and Leon Glass’s dot patterns (1969) are our own drawings of the ideas.

Colour palettes

The 31 palettes are colours read from historical sources. Colours themselves belong to no one; the sources are credited here.
