Strømg Lump Leaks is a ceiling lamp designed by Lamp Lumps (LL). The used technique is self supporting interlocking of pieces (without gluing, screwing or nailing) of 547 different pieces of polypropylene routed with a three-axis CNC. The conception and materialization is mixed by using digital and analogue means. The first name Strømg is the junction of the English term strong with the Danish surname Strøm. Strong, because it is a robust three-dimensional puzzle witch form is the result of small variations in each of the pieces. Strøm, because this work is an homage to Holger Strøm and his IQ Lamp. The Lump Leaks surnames suggest, for instance, the leaking drops of water or the leaking of information. The abstraction of the concept results, morphologically, in a piece that is the materialisation of the metaball modeling technique that was widely used by pioneers of digital media in architecture in the 90’s.
