Next to the possibilities of digital form-finding strategies, parametric design and computational visualization techniques, which lead to an increasing virtualization of our society - rapid technologies allow today for the direct translation of the digital model into the physical world. As a result of this process the experience of digital realities, driven by virtual environment gets an interesting shift back to the physical world. Against this background the paper points out that it is a question of design to define contemporary and intended matters, processes and strategies of interaction, in other words: to inform the design.
