Whorld is a free, open-source Windows program that offers a unique approach to creating live digital art. Whorld generates real-time animation, but unlike most visualizers, it's designed for performing, and includes MIDI support and other features more commonly found in clip-based VJ programs. Whorld animates sacred geometry, and distorts it according to parameters that can be adjusted manually, or automated via programmable oscillators. The result is a mesmerizing, psychedelic composition of continuously transforming shapes. For details, sample movies, and to download Whorld, visit whorld.org
