Live coding
Live coding is the name given to the process of writing software in realtime as part of a performance. Historically, this technique has been around since computers were used to produce early computer art, but recently it has been explored as a more rigorous alternative to laptop DJs, which lacks the charisma and pizzazz of musicians performing live.
TOPLAP, an ad-hoc conglomerate of artists interested in live coding was set up in 2003, and promotes the use, proliferation and exploration of a range of software, languages and techniques to implement live coding.
