TRACE

TRACE is an interactive art installation that explores the interplay of time, movement, and human agency through the visualization of light trajectories. Utilizing long-exposure photography, the installation captures dynamic pathways of light as they are traced through space, creating unique patterns shaped by user interaction. A control unit, equipped with eight analog sliders, enables users to manipulate variables such as speed, direction, brightness, and quantity of light sources. Each slider offers 512 discrete resistance values (9-bit resolution), yielding approximately 4.72 sextillion (4,722,366,482,869,645,213,696) unique combinations. This vast potential ensures that even subtle adjustments produce distinct light signatures, emphasizing the individuality of each user’s interaction.

The installation draws a conceptual parallel to celestial motion, where stars trace predictable yet ever-shifting pathways across the night sky due to Earth’s rotation and orbit. Historically, civilizations like the Babylonians (c. 3000 BCE) systematically mapped these stellar trajectories, a practice echoed in TRACE’s methodical capture of temporal pathways. By enabling users to actively shape light patterns, TRACE reflects on the traces we leave in time and space, offering a tangible means to document and author ephemeral moments. The installation thus serves as both a technological and philosophical exploration of agency, temporality, and the enduring impact of human presence within a dynamic environment.
