In this paper we examine some of the main characteristics of the transformations induced by digital culture. Our argumentation is based on a triple point of view. First we reconsider the architectural form as a significant instant inside a sequence of potentialities. Second we mark the renewal of the notion of ornament and its inscription into the digital culture. Third we return to the fabrication-conception continuum and we note the abilities of tools and technologies to stimulate perceptual entities. Finally we illustrate these topics with two examples of architectural algorithmic design. Based on these examples, we will mark the links between intuition and computation and the emergence of a digital materiality.
