Designing with Fog traces the development of 10 Kinds of Fog: Prototypes, a set of ten ephemeral, dynamic, and environmentally- responsive fog sculptures. Developing the installation required that, as designers, we had to find fog – that we go on a journey from seeing fog as a carrier and enabler, to seeing it as a material with properties that can be explored and designed with. It built on a proposal for an immersive, multi-sensorial Fog Garden, in which fogponics carried plant nutrients. Explorations into ways of delivering, shaping and releasing fog in relation to the plants led to an increasing understanding of fog’s own behaviour. Finding fog was thus attuning to changes in buoyancy, litheness and opacity arising from the relationship between materials and the environment.
