Place-A-Trace explores the theme of feedback through the idea of impressions—how people leave marks on one another, on places, and on shared spaces. At its center is a machine that invites participants to create drawings in sand, a medium chosen for its natural ability to receive and reflect touch. Sand records every interaction but never holds it permanently, echoing the transient nature of feedback and influence. The machine acts as a symbolic filter, representing the personal lenses through which we process experience and connection. Evoking nostalgia, the drawing machine recalls a familiar childhood toy, connecting us with early moments of spontaneous creativity, exploration, and impermanence. Whether engaged with alone or in groups, each interaction becomes a fleeting yet meaningful trace, emphasizing the quiet power of impact and memory.
