AW21 ‘Unstable Equilibrium’ Collection Development Book. The development book is a tactile reference to the HELIOT EMIL design process and abstract realisation of ‘Unstable Equilibrium’. A combination of analogue and digital graphics, development sketches and drawings show the collection’s themes, painting a story of equilibrium, juxtaposed balance and symmetry. The transparent pages can be deciphered by underlaying the metal sheet provided.
