Brecht is a VJ tool written in Java and OpenGL that uses SQL (Structured Query Language) queries and Java instructions to trigger and mutate live visuals -- text and images stored in a MySQL database.

An unique feature of Brecht is the command shell which is superimposed over the visuals generated live from junk data. Queries and code typed in real-time, logs of server transactions and syntax errors transcend their textual form and become narrative gestures. The process of navigating the database becomes transparent, contrasting the way databases exist today: an ubiquitous, yet hidden cultural form.
