The shop presents our attempt to form a retail space into a lattice envlosure generated through the assemblage of a single module - a perforated Penrose metal tile in 72 degree parallelogram. Jewel showcases of various shapes and sizes are generated by the same modules and are supported merely by the metal lattice itself. The floor is left blank to receive different future artworks. The complex Penrose sheer with the experimental approach of "skin as structure" results in a piece of negative sculpture where art and function converge.
