This project used free census demographic data to create an interactive data visualization. The visualisation allowed users to select data sets on a touch screen which were then projected as coloured bar graphs onto the rooftops of a miniature suburb. Two graphs were selectable and were always compared the the data of the city as a whole. The work was created in collaboration with Simon Nicholls. The projection screen was actually a three dimensional miniature suburb created using 3d modelling and laser cut sculptures.
