Litico Ludico is an experimentation of stone material processing starting from the use of numerical control machines (with 5-axis technologies of Helios Automazioni). The object looks like an informal seat but at the same time becomes, thanks to its forms, a recreational use for children and adults who can use it due to the sinuousness of the realized shapes. Massimo Russo's project, with the coordination of Architecture Department of Pescara, try to combine some main aspects in the production of stone design objects with new digital technologies. In particular: parametric design with algorithms, optimization of the structural component and definition of the machine language; the processing of materials with the technological interface of the new cutting machines; the possibility of composing / decomposing the individual pieces of the production of the object in the articulation of different possible solutions of use.
