OXALIS - Mareike Pittig

OXALIS is a foil-welded light object whose three-dimensional form is defined by pneumatic pressure. Its stability is derived from a geometric structure of inflatable ribs. Inside, loose particles create a fluid, organic texture, while the lightweight body is only supported by its delicate cables.

The design draws its inspiration from plant physiology: specifically, the turgor effect—internal cell pressure that allows plants to move. It is this mechanism that causes the Oxalis triangularis to fold its leaves at night. Mimicking this natural process, the light uses air pressure to transform both its shape and function. As the pressure gently subsides and the form closes, the atmosphere shifts from functional brightness to soft diffusion. OXALIS transcends the role of a traditional lamp; it physically manifests the transition from activity to rest.
