By means of 'Design by Emergence' an oblique interface is proposed, feathering out the edge between the vertical Marconi Towers the horizontal city of Rotterdam.

Design by Emergence is a rule-based design approach where the designer designs (interaction) rules for building configuration simulations, shape grammars and building components. The emergent outcome is evaluated an rules are (re)designed and parameters adjusted.

The oblique interface builds on the theory of 'Fonction Oblique' by Parent and Virilio and various built implementations from e.g. Zaha Hadid, UN-Studio, OMA. It also addresses the theme of 3D-Mat buildings.
