EWall is an interactive installation that enables the concept of inhabitable interfaces. Basically a building is transformed to a maze display which can be used for collaboration over distance or in presence:

EWall proposes a computational solution to help problem solvers work faster and produce smarter solutions through easily collecting, organizing and viewing graphical and contextual information. It will also facilitate user collaboration in large, distributed and decentralized teams while maintaining individual ways of working.

An interesting concept was the idea of building an EWall Operating System for the personalization of the kind of interaction with the wall:
