– interactive sound installation demo
PulseCubes is an interactive sound installation. Visitors are invited to become part of an implicit feedback loop whose other components include a set of small cubes on a flat surface, computer vision and digital signal processing. The cubes are tracked by a web camera positioned overhead and processed through a partially opaque system implemented in the programming environment Max/MSP/Jitter.
Visitors have the opportunity to influence and interfere with the notion of time by playing with the cubes. Their placement and movement affect features of the audio such as rhythm, tempo and synthesis parameters as the passage of time is stretched and constricted. A chain of indelible “traces” are left in the position of the cubes and the resulting sonic environment and physical vibrations.
PulseCubes was part of The Dissolving Cube at the Portman Gallery, London in Nov-Dec 2009, re:new Digital Arts Festival, Copenhagen in May 2010 and Sound Travels Festival of Sound Art, Toronto in Aug 2012.

Construction in Self is a generative work based on the Lorenz dynamical system. It has sensitive dependence on initial conditions, giving rise to what is commonly known as the “butterfly effect”. Its generative form is suggested by this property and the work takes an input prior to performance as initial conditions from which a different piece is produced each time. A diverse variety of behaviours are observed ranging from periodicity to chaos that yield interesting results as signal, control and meta data, suggesting a self-similar microcosm that is complex yet deterministic which can be replicated from the same initial input. The title is a reference to John Cage’s Construction in Metal series (1939-42) in which simple sequences of numbers – referred to as “rhythmic structures” – are used as a basis for structures at different time-scales.
Construction in Self has been performed at noise=noise the Basement Series 2009, London, ICMC 2010, New York, CONTEMPORANEA 2011 ‘Japan 2011′ Festival di Nuova Musica, Udine and 希/日 GR/JP at Het Nutshuis, Den Haag.
