The piece

15 is a participatory light art installation created for Carbon Events’ 15-year anniversary celebration. Across a two-metre wooden panel, 120 individually bottom-lit glass jars form a low-resolution screen that can spell out the number “15” — but the image only completes when the guests do. Each visitor draws their own illustration directly onto a jar and screws a small bulb into the surrounding frame, so the work slowly comes alive over the course of the evening as the room fills.

Every jar is lit by an addressable LED module, controlled wirelessly so the whole wall can shift, pulse and animate in sync. The result sits somewhere between an artwork, a guest book and a shared ritual: a hundred-and-twenty individual gestures that only become a single glowing image together.

15 was unveiled on 11 November 2026 at Carbon’s anniversary at Triple C in Amsterdam. Afterwards it moves to Carbon’s office, where it hangs permanently and can keep growing: new drawings can be added over the coming years.

15 continues a line of work that uses light and technology not as spectacle but as something that brings people into the same room — and asks them to add to it.

From the workshop

Two sheets of plywood, 120 holes

The two plywood panels standing side by side in the workshop at night, cut through with a grid of 120 rectangular openings — twelve columns, ten rows.

Each jar sits in a custom-designed holder, 3D printed with carbon-positive filament made from recycled fishing nets — nets that would otherwise be polluting the ocean.
