Cube is an interactive sound installation and performance platform by Khrystyna Kirik and Nick Acorn.

A semi-open structure invites visitors to enter, pass through, or stay inside. Distance sensors on upper corners of the Cube respond to proximity and movement, translating them into a shifting four-channel sound field.

There is no fixed composition or performer. Sound emerges through presence: movement, pauses, and encounters continuously reshape it. Each interaction leaves a trace, without repeating.

Cube functions as a shared instrument — not played, but inhabited. Sound arises between people, materials, and movement.

Presented at Brave! Factory Festival 2023, Kyiv.
