Rafa Diniz is an artist and computer art educator who lives in Crato, northeastern Brazil. Although his formal studies are in music, Diniz is primarily a computational artist both in terms of image and sound. His work focuses on generative, interactive visual, and audiovisual art, produced mainly through programming languages. 

From 2020 he began a series of remote classes on creative code for the Códigos Fazem Arte platform, with students from all over the world taking part.
