2. Mapping Hertzian Spaces Does ‘Hertzian Space’ largely lack spatial logic? Is it possible to visually map it with accuracy? What are the implications of revealing the invisible data-flows for architecture & urbanism and a number of other disciplines? ‘Wi-Fi Camera’ takes “pictures” of spaces ‘illuminated’ by Wi-Fi, revealing thus the electromagnetic space of our devices and the ‘shadows’ we cast within such spaces. Bengt Sjölén and Adam Somlai Fischer with Usman Haque

3. Challenges & Opportunities 1_ Visualisation systems contribute towards our understanding of invisible phenomena, revealing unknown patterns, invisible or non-existent environments. 2_ More sophisticated viualisations “embracing” “the ubiquity of data visualisations of social phenomena” are needed (CASA, UCL). 3_ Error / uncertainty in the data may derive from the data quality and/or model assumptions. 4_ Uneven datascape (despite a decentralised ad-hoc and peer-to-peer mesh-structured Wi-Fi network proposal in 2004 by Bar & Galperin, e.g. fibreoptics protect the City of London’s network from algorithm delays) 5_ Balance overambudance & scarcity of data when visualising the “ footprints ” of our interaction with the urban environment & digital infrastructures (e.g. taking and sharing digital photos, accessing Google maps and My Location, wireless network communication, etc).

4. Open-source Urban Network Analysis Toolbox for ArcGIS. Spatial analysis on urban street networks similar to social network analysis. Human interactions: ‘links’/paths along which travel can occur, ‘nodes’/intersections where two paths cross, and buildings, where most human activities take place. These 3 elements are used to describe the spatial relationships between people, places and institutions.

12. Gregg Lynn: Phase space "Phase space": a deep dynamics space of operative 'tracings' through "active interactions", shifting from "autonomous purity" to "contextual specificity". Its 'instances' emerge in a gradient field of potentiality. http://www.digicult.it/en/digimag/issue-067/operative- transformation-part-2/ Port Authority Gateaway (sweep) - 1995

13. Gregg Lynn: Form as site - “Flat-earth stasis“ ’ - Complexity - Formal purity - “Collaboration of enfolding a - Autonomy context & unfolding an object." - Mere visual ‘phenomena’ - “Curved gradient tectonics" storing virtual force & motion. Form: a complicated and evolving site where multiple forces are operating. http://www.digicult.it/en/digimag/issue-067/operative- transformation-part-2/
