Echo is the working title of an ongoing material research into creation of shape by repetition. The base of the project is a physical material which Hess alters into sculptural timelapses in his digital world. The project is named after a common software filter which uses the history of movement to visualize its journey through time.
Hess first started the research as part of a commission by the Dutch National Glassmuseum in Leerdam. By using see-through plastics such as balloons and foils Hess created an animation in which a human body gets captured by shells and shapes of what appears to be liquid glass.
