ABSTRACT This article addresses the design of the Blippoo Box, an audio sound generator that operates according to the principles of chaos theory. By designing the Blippoo Box, the artist attempts to bridge a crossover space between abstract (sonic) art, music and artistic craftsmanship. In the hands of performing musicians the Blippoo Box becomes an electronic music instrument that invites performers to improvise with the chaotic nature of the box. Despite this chaotic behavior, the produced sounds have particular characteristics that are roughly predictable and enable a performer to build a performance around a composed scheme.
