Metropolitan Waves is an imaginative series of four elements designed on the basis of the modularity of three-dimensional blue tiles. These four elements can rotate and integrate freely, allowing the creation of compositions adaptable to any environment, perhaps even to street furniture. The name of the project draws inspiration from the changing skyline of metropolitan cities and these small skyscrapers can be used as pedestals, free-standing tables or parts of more complex compositions. Special attention is paid to the colour of the joints, in chromatic harmony with the objects themselves. This reuse initiative also promotes an ethical and conscious approach to design.
