Elevate your space with 'Sponge', a wall-mounted light sculpture that exists at the intersection of algorithmic logic and organic chaos. Produced under the Solid Difference label, this piece is a testament to the power of additive manufacturing to realize geometries that were previously impossible to fabricate.
The 'Sponge' is not just designed; it is engineered. Its hemispherical form features a complex, non-linear distribution of apertures inspired by the stochastic patterns found in marine Porifera. Each "pore" is a precision-engineered light guide, mathematically optimized to balance structural integrity with maximum lumen diffusion. The result is a tactile, matte-white surface that looks like a high-end architectural model by day and a complex light engine by night.
The 'Sponge' doesn't just illuminate a room—it redefines the surrounding surfaces. Due to the specific conic geometry of the 3D-printed internal channels, the light is collimated into a stunning radial array of soft-focus beams. This produces a low-glare, high-contrast shadow map on your wall, creating a meditative visual rhythm that mimics the "caustic" light effects seen underwater.
The genesis of 'Sponge' lies in a deep-dive through design history. Inspired by a rare, long-out-of-production piece from a (probably) Dutch lighting pioneer, we wanted to bring this aesthetic back to live. While the original manufacturer has faded into history, we have used modern CAD workflows and high-resolution 3D printing to evolve that vanished vision. We’ve replaced traditional industrial constraints with the limitless possibilities of parametric modeling.
Every Sponge is handmade on demand in Switzerland. Please give us about 3 weeks lead-time to produce each sponge.
