The PebbleBox and the CrumbleBag are examples of a gran- ular interaction paradigm, in which the manipulation of physical grains of arbitrary material becomes the basis for interacting with granular sound synthesismodels. The sounds made by the grains as they are manipulated are analysed, and parameters such as grain rate, grain amplitude and grain density are extracted. These parameters are then used to control the granulation of arbitrary sound samples in real time. In this way, a direct link is made between the hap- tic sensation of interacting with grains and the control of granular sounds.
