Named for its three-layer construction, Tri-P stacks three laser-cut metallic sheets, each with its own angular geometry, so their patterns overlap and interfere, with density built from collision rather than any single layer. The result sits close to mashrabiya in function but sharper in language, closer to fractured glass than classical latticework, filtering light unevenly as the layers shift with the eye. Mounted as a sliding element, it works less like a fixed screen and more like a moveable threshold.
