MEDIATED ARCHITECTURE: Vivid, Effervescent and Nervous, the second issue of the SAC JOURNAL, presents three projects de- signed at SAC during the last eight years. The three projects are: The Theatre of Immanence (2007), an installation and exhibition project in Städelschule's Portikus gallery; Digital Bodies (2013-14), an experimental research project; and Orkhestra (2014), which was an installation on a large, public square in Frankfurt and part of Luminale, 'Biennale of Lighting Culture'. The projects vary in scale and nature from gallery installation via laboratory-style modelling experiment to an urban intervention. They span a period in which architecture's contribution to the production of space has become increasingly me- diated by technology. Each in their own way, the three projects probe this condition and explore new design opportunities given to archi- tecture. The results are vivid, effervescent and nervous - and always a mediated architecture. Accompanying extensive portfolios of drawi- ngs and pictures that document the respective design processes and their results, are texts that expound on the theoretical and practical implications of each project
