Abstract
The authors describe an installation that was shown at the exhibition The Best of All Possible Worlds at Technische Sammlungen Dresden in 2016. The installation provided an interactive experience of the evolution of a complex bicontinuous structure of two immiscible fluids. The evolution is driven by the surface tension of the interface of the two fluids, which results in a continuous reduction of the interface area. The process is mathematically described by a partial differential equation, which is numerically solved. In each time step, the structure, visualized by the fluid-fluid interface, is rendered and shown on an elastic display. According to the deformation of the display, the corresponding time frame is projected. By pushing against the elastic display, one therefore can interact with the structure and evolve it in time in a playful and intuitive manner.
