GranulatSynthese is an interactive tabletop installation for the intuitive and haptic creation of ambient, meditative audio-visuals. It uses granules distributed over a surface with projected visuals and generated sound. A haptic, visual, and auditory landscape can be explored and composed intuitively. This installation is calm in that it supports a meditative experience and fosters mental rest and self sufficiency.  (Beckhaus, Berghoff, Schröder-Kroll, - im.ve lab, University of Hamburg 2007)
