Interference is a series of large-scale textile works exploring the impact of the moving body on air in architectural space. A single hand is isolated in the act of unfurling, its upward and downward arcs traced in two dimensions. Air is considered as liquid, and the wake of the hand is traced in a series of radiating lines marking both time and space. Architecture offers itself as a containing edge, continuously reflecting the displaced air within itself. Over time the bounded space develops an invisible turbulence; a complexity that belies its apparent stillness. This work reflects upon different modes of space-making and is developed from an encounter with textile artist Machiko Agano in Kyoto in 2006. Air is considered as the primary substance of architectural space, and its invisible disturbances and trajectories are made visible as alternative forms of structure. This work is an architecture of body, air and motion; it is an architecture drawn from the barely perceived consequences of our movements within air.
