What is a tunnel?
A tunnel is a way to get to a destination. Tunnels are used for convenience; they are placed at a certain location to make journeys shorter, and easier to get to. The main function of a tunnel is to cut time, to save time and to improve ways of getting to a destination. A tunnel only has two entrances; a way in and a way out. Once you enter that space, you can either continue all the way or you can turn around and leave the way you came.
How could one create an exhibition, or a site-specific piece of art in a tunnel?
The idea of a tunnel offers a lot of room in which to create both these things. It is a space that people pass through; most people would not take into consideration the affect that this passage has on their daily journeys. By creating an artwork that revolves around the concept of awareness, it would be a way to almost force some people to broaden their scope on the city around them. Installation artwork in its basic form is about interaction with an audience.
This exhibition would be a way that people could interact with the artwork with out any preconceptions attached. As they entered the tunnel, they can either walk all the way threw, interacting with the work as they move or they can leave and go another way to get to their destination.
The tunnel is a physical, real world setting. It is not a ‘established’ place, not controlled by an institution (in relevance to art establishments) but an open place, made for and used by the public. This project proposed the idea of interaction; it aims at becoming a site for the curator (us), the artist and the audience to collaborate.
