The act of cracking knuckles often stems from psychological tension, nervous focus, or the satisfaction of release. Crackers explores how this habitual and often unconscious gesture can be transformed into a tangible interface for emotional reflection. The project collects data—including the auditory sounds of cracking joints from different body parts, along with their associated emotional and physical contexts—and embeds these qualities into a constellation of handcrafted ceramic artifacts. Each vessel is sculpted to either amplify or soften the sonic characteristics of cracking, mirroring the intensity or subtlety of its emotional origin. Equipped with motion and distance sensors, the ceramics respond to presence, absence, and touch, generating personified interactions that evoke feelings of tension, frustration, excitement, joy, or relief. Crackers externalizes a private bodily impulse—typically hidden or dismissed—and brings it into a shared, public space for expression and discussion. Positioned at the intersection of personal memory and collective empathy, the project invites new rituals for emotional regulation and interoceptive awareness.
