Pump Action Pixels are a group of artists devoted to making electronic music with computers analogous to their environment. This means producing tightly synchronised music to mirror movement or other stimulus and (at the other end) visuals to mirror the music. For instance, their latest project is an attempt to create music that reacts in direct correlation to atmospheric data fed from a portable, PC-based weather station. Members are: Mr Squiggle (Department of Social Engineering) Oktalz (signal-to-noise, Fierce Throat) Minerva (DoSE) All are agents for the UndesirablePropagationUnit.
