This evolution is articulated in four complementary blocks: man, the city, the collapse of the straight line, and the return to nature. Man, uniformed in dark suits, possesses creative power but remains subject to the very surroundings he has designed and domesticated in order to feel sheltered from potential external threats. This illusory sense of safety leads him to lose contact with himself and wander disoriented within his own labyrinth. The city becomes a prison in which the crosswalks represent the final and most perfect distillation of the urban sign, capable of articulating and musicalising the everyday motions of man. The collapse takes place when man realizes that the straight lines used to build his refuge have become the very bars that confine him. In order to escape, he surrenders to the weight of matter that condemns him to reality, and blends into the asphalt. The journey home, the journey back to nature, thus begins.
