Echoes can be interpreted as a forest and its reflections, ripples of sound wandering around a reflective surface, real-world and underworld.
Echoes plays with the materiality of paper. Structural, but not rigid. Flexible as something foldable, bendable, rollable, stretchable.
Control experiments on the number of turns, heights are conducted to study their correspondence to the resulting shapes.
Topographical quality is naturally generated through the tension between supporting struts and paper spirals.
