Touches and strokes generate visualizations and sounds which evolve in time.User defined parameter and color schemes can be used to explore the manifoldness of the underlying particle system.The compass can be used to locate the following instruments in the four directions of the winds: Balalaika, Celtic Harp, Guitar, Gamelan, Guzheng, Kalimba, Koto, Marimba, Orchestral Harp, and Sitar. Each of these instruments can be assigned to a compass direction with a double tap on a cardinal point.The acceleration sensor is used to simulate the impact of gravity on the flowing particles. (You must increase the impact of gravity in the parameter settings to see the effects.) Other parameters can be used to control the duration of the sounds. Endless loops, for instance, can be created by a reduction of the evaporation parameter and an increase of the elasticity of the particles.
