Three Corners of the City is a real-time interactive data visualisation displayed on a large-scale media wall that connects three local communities in Melbourne across place and across time. Live data touchpoints record people walking in each community in an interconnecting flow of everyday life, breathing life and form into dynamically evolving motion graphics. The project engages communities with smart city data visualising it in aesthetically pleasing and tangible ways. Postcards were also designed for community members to engage further with the work in the form of citizen activations.
