The origin of the word perforation is Latin and it is constructed of the two parts per (through, during in time, because of) and foramen ( = hole), so it could mean through a hole or even because of a hole. In this proposal it is intended to not only understand the term as a description of a material being penetrated in a way that it has many holes and by a permeable or a predetermined breaking line, but also in the word by word meaning from its Latin origin with light sticks that pierce the walls of the buildings. The light lines that cut through a hole in the building are a metaphor for the act of traveling, which always cut through the unknown and sometimes even has to break barriers or walls. Which place is better suited to carry a metaphor for traveling then the site of traveling itself? Traveling takes us further, it teaches us, it makes us strong but it also implies that we are courageous and not scared of going headfirst through the wall. In this proposal, light lines are sent through a hole. They create the hole to go through or because of a hole they are able to get to the other side. Maybe even during time the hole exists and the light lines are actually timelines.
The general concept for this proposal is to take the idea of a perforation to another level. Instead of only punching holes into the metal sheets, it is proposed to penetrate walls and roofs with light sticks that are white lines during daytime and bright lights during the night. The light sticks shall be made with high efficiency but low consumption LEDs to minimize energy needs and to diminish the carbon footprint of the artwork. Through these piercing light lines, the attraction of the buildings gets elevated and the stations are not only distinctively recognizable from long distance and also by night. Moreover, in combination with the already remarkable architecture they become a distinguished landmark. The notion of a light line through a wall implies the association of high speed and movement in the direction of the line. The names of the stations shall be placed in an upper corner of the buildings. Each single letter shall be a separate, slim light box illuminated by internal cold white LEDs. The placing of the names on each individual station has to be decided in such way, that it is visual from the neighborhood roads and not in competition with the artwork.
