Design By Numbers (DBN) was developed for teaching general programming concepts to artists and designers with no prior programming experience. DBN is an extremely minimal language and environment, thus making it easy to learn but limited in its potential for creating advanced applications.
DBN was originated by John Maeda, director of the Aesthetics + Computation Group (ACG) at the MIT Media Laboratory. Processing originated in the ACG and many years of experience developing and teaching with DBN informed its development.
DBN is free and can run inside a web browser. More information is available at http://dbn.media.mit.edu
