I began the ongoing mobile project in 2003. Although many of my works involve some type of openness (changeability or indeterminacy), this series of works explores a specific kind of openness, the mobile. The goal here is to compose a new mobile every year, each with a unique instrumentation, and each with its own way of being mutable.
