The physical trace of an object or of an event is not always visible in its entirety. The visible and the invisible are often 2 sides of the same coin and as creators it is important that we value and take into consideration both sides of the entity. Take for example the ‘Process’ and the ‘Object’. We don't always see the process behind the formation of an object but we can see the ‘Trace’ of the process in the final product. In some cases, the visibility of the process is completely concealed, invisible to the naked eye. Whilst at other times we do not need the final object and it is the process that we need to experience.

What if something had happened, something extraordinary, how would we know it really did occur? Without witnessing it ourselves we need to see at least a trace of the event, an aftermath. Murder scene for example, there is no body, we don't see the murder take place, but by the line drawn around the body, the police tape around the scene, perhaps the disturbance to the objects in the environment. From a variety of clues, from a selection of evidence the trace becomes
visible, the event becomes imaginable. A narrative ‘outlines’ a sequence of events, in a sense it traces the paths of characters until a complete story is revealed.

Architects also work with empty spaces, and in order to create new buildings old buildings are destroyed. The architect can leave a trace or evidence of the old building or completely
annihilate what existed before. The architect through the process of renovation makes an interesting collaboration between the trace of the old building and the addition of the new. Strangely we can still sometimes find the traces of buildings, people, places and things that have
been erased or disappeared.
