In recent years, screens are being reimagined not just as windows for information but as presences that fill space. The Norwegian public broadcaster NRK’s twelve-hour fireplace program became an unexpected hit, and platforms like Netflix and YouTube now feature endlessly looping scenes of fire, waves, or rain. People are moving away from efficiency and purpose, returning to the quiet act of watching light and feeling time flow within a space.

This sensibility echoes the aesthetics of the screensaver—software meant to let the screen rest, yet it drew our gaze to the poetic accidents of computation. Coded Fireplace brings that spirit into the present as interior media. Just as Erik Satie’s “furniture music” and Brian Eno’s “ambient music” reframed sound and space, we position generative art between image and space—furniture for the eyes.

Coded Fireplace (Prototype)

Size: W131 × D131 × H80 mm
Material: PETG resin, PLA resin, natural marble
Weight: approx. 480–1440 g (varies by cover material)
Battery: 5000 mAh (approx. 3 hours operation) *Battery life may vary depending on use and conditions.
Charging: USB-C
Video Out: mini HDMI
Processor: Broadcom BCM2712
Patent Pending in Japan

This prototype was built to validate the concept. A battery and compute module are integrated in the enclosure; visuals are generated from device metrics (CPU usage, temperature, battery level) and output via mini HDMI. Each unit includes a unique program authored by an artist. The artwork differs per device and continues to evolve over time.
While this version uses an off-the-shelf SBC and is slightly larger, development indicates a clear path to miniaturization via a custom board.

Coded Fireplace is a prototype of a new visual medium jointly developed by Dentsu Lab Tokyo, BASSDRUM, and NEORT. We’re seeking partners to bring this vision into the world.
Core technologies are patent pending. Under NDA, we can share additional details during partnership discussions.

Product & business partners:
Manufacturers and brands interested in co-developing design, manufacturing, distribution, promotion, and exhibitions.

Collaboration partners:
Organizations exploring spatial installations—across retail, hospitality, and museums—and the development of new brand experiences.

Artists & creators:
Those who want to use this device as a new medium and explore novel forms of distribution and exhibition for generative art.

From “window of information” to “presence that fills space.” We hope Coded Fireplace becomes the next canvas connecting art and technology. If this resonates, let’s take the first step together.
