Once, in the computing rooms of the Lethaby buildings, an art and design student described objects and space as dwelling places for thought forms. The thought form can either be independent or collective. Once it reaches enough consensus, it takes material form and, until it is necessary or justified it will persist. Its story can be fuelled by novelty, love, necessity or nostalgia. When eventually the story fades and its memory starts vanishing, its material form decades and gives up its matter to a new form.
