Day/Dream is a collaborative spatial project on Sunset Boulevard by artist Sara Suárez and architect Regina Teng. The project originates from concepts of perception and fluidity, dreams and collectivity, and complements M&A's Heat Aid initiative that addresses water and shade inequity through gathering and redistributing crucial resources during hot months. Day/Dream collapses layers of optical design with immaterial and ephemeral phenomena: while Suárez orchestrates a composition of community-sourced dream narratives and imagery across the space, Teng uses lenses to cast watery refractions and modulate light’s thermal effects. In a moment when our needs for liveable environments and new relationalities are increasingly urgent, this convergence of practices explores the radical, material potentials of seemingly ephemeral phenomena.
