What if your mood could travel with you without requiring an explanation?

TORU Systeme, a retro-future concept by Caon Design Office for Smuggler, approaches emotion through two wearable objects that communicate without words. One is a circular wrist device whose light changes colour according to the wearer’s emotional state. The other is an open-ear audio piece designed to let the surrounding environment remain audible while mixing it with whatever is being played.

At O Days Festival 2026 in Copenhagen, sound takes a strangely quiet form. Speaker, a new installation by Copenhagen-based studio Frederik Gustav, borrows the unmistakable geometry of a loudspeaker and removes everything that makes it function as one. No sound comes out of it. Instead, the piece catches light, bodies and fragments of the surrounding festival, turning a familiar piece of audio hardware into a large-scale visual surface.
