CityTomography

"CT, City Tomography, is a project to reconstruct visible or invisible aspects of urban spaces as a

 three dimensional “information city”
 and explore it just like a computerized tomography
 (CT) of the human body.  CT will provide
 information about the city by the way visitors
 cannot perceive from a physical urban space. It will
 enhance an overall image of the city through a
 reciprocal relation between a place and information."
