Despite their very basic functions, toothbrushes typify a highly diversified, and often cryptic, universe. Design, terminology and features embedded in these everyday objects remind some recent technological developments. This applies in particular to optical fibers whose products sound almost supernatural. Starting from this observation, the goal was to show how extrapolations are pivotal in the creation of a collective imagination. Thus, the principle adopted was to select and apply the enigmatic products descriptions made by optical fibers manufacturers to the toothbrushes photographed by Maxime Guyon. This lexical substitution brings together two regimes of contemporary commodities that belong to radically different regimes but, in many aspects, share the same languages. 尽管它们具有非常基本的功能，但牙刷代表了一个高度多样化，通常是神秘的宇宙。 嵌入这些日常物品的设计，术语和功能提醒了一些最近的技术发展。 这尤其适用于其产品听起来几乎是超自然的光纤。 从这一观察出发，目标是展示外推是如何在创造集体想象力中发挥关键作用的。 因此，采用的原则是选择并应用由光纤制造商制作的神秘产品 描述到Maxime Guyon拍摄的牙刷。 这种词汇替代将两种属于完全不同制度的当代商品制度汇集在一起， 但在许多方面，它们共享相同的语言。
