Since the beginning of the 20th century, neon-lamps are enlightening our nights, and are attracting our attention in the darkness. At the beginning, mainly used for advertisement and commercial communication, especially in American cities, the shining sources became symbols of nightlife, modern consumerism, and the fast pulse of western urbanism. Since the 1980’s though, neon increasingly was exchanged with other technologies and techniques, so that today, nearly totally erased from our urban matrixes, it has a melancholic and anachronistic character.
