Digital poetry is a form of New Media Art and an interactive evolution of traditional poetry created through the use of computers and digital technology. While some may consider any poetry created electronically to be digital poetry, the main creative use of the medium is to provide an element of interactivity without requiring direct contact between the poet and the audience, as would be necessary to creative traditional poetry in an interactive manner.
One example of digital poetry is JABBER: The Jabberwocky Engine, which is a Java program created by poet and new media artist Neil Hennessy. The program uses lexical rules to combine letters into nonsensical words that actually follow English pronunciation rules and norms and therefore sound like real words even though they are not.
