This category of Music Toy is being designed as an inexpensive, stand-alone, sound-producing, and manipulating device that gains power when networked with other Simple Things. Each Simple Thing is hand-held, and contains several buttons and a single continuous pressure controller. Sound memory and a simple processor allow the storage of waveforms, and their modulation or manipulation. IR links allow sound to be exchanged from one Simple Thing to another, as well as for Simple Things to be synchronized in large numbers. We are conducting experiments in the use of large numbers of Simple Things in physical proximity, and as remote music controllers via the Internet. In addition, we are exploring the use of Simple Things as a means of bringing personalized music and musical information between public performance experience spaces and home.
