A Pure Data (http://www.puredata.info) egy szabad és nyílt forráskódú, valós idejű grafikus programozói környezet, amelyet széles skálán alkalmaznak művészek a vizuális művészetekhez, színházhoz, tánchoz, hanghoz, installációhoz, perfomanszhoz és egyéb kísérleti médiaművészeti
alkotásokhoz.

A Pure Data ideális azok számára, akik szeretnék a digitális technológiát munkáikba integrálni, és képzett médiaművészek számára is, akik új eszközökkel és módszerekkel szeretnék kombinálni eddigi tapasztalataikat. A Pure Datával könnyen készíthetőek interaktív környezetek, valós idoben generált zene és kép, könnyen összekapcsolható a vizuális tartalom a hanggal.
