The work is based on a modified Lorenz attractor, a three-dimensional dynamical system derived from a model of atmospheric convection, and implemented in the programming environment Max/MSP Jitter. During performance, parameters are modified in real-time. It is sensitive to initial conditions, and seemingly insignificant deviations produce widely and unpredictably differing results. This gives rise to what is popularly known as the “butterfly effect”, where a butterfly beating its wings may produce a hurricane, but also due to the attractor’s lemniscate-shape. However as it is deterministic, the same passage can be replicated by reproducing the same initial conditions.
A diverse variety of behaviours are observed, ranging from periodicity to chaos, that yield interesting results as audio data, either as signal data in nonstandard synthesis or control data such as rhythm and pitch. The visuals are also derived from the same process producing an alternative representation in three dimensions as well as emergent phenomena such as the Moiré effect.
