The article describes the making of an art piece combining stone sculp- ture and digital fluidity. The motivation for this simulation was to enrich the usual static format of a stone sculpture with a dynamic dimension. Such digitally enriched sculpture should resemble water droplets running over the stone surface while obeying physical laws. The 3D surface of a specially designed and carved stone sculpture is continuously captured by the Kinect range sensor. Each water drop out of many thousands, which are introduced as rain drops falling evenly distributed over the sculpture, are simulated individually to run over the stone following the maximal gradient of the 3D surface. These simulated water drops are then projected as light points with a video projector on the surface of the sculpture. An admirer can enjoy the haptic experience of touching the stone surface while observing a digitally generated but physically grounded ever-shifting fluidity
