Transpiration is a semi-permanent real-time data-driven projection currently on view in the courtyard of the landmark building 240 Central Park South in New York.
Twenty-seven branches on the tree represent the twenty-seven floors of the building. Four lines moving along the trunk mimic the movement of the elevators in the building. As people get off the elevator onto a specific floor, that branch grows and becomes more complex. When people leave a floor, the associated branch diminishes.
Tenants can see this exterior courtyard space from their windows and as they move through the rotunda of the building. Transpiration is intended to evoke the feeling of Central Park and transplant an element of the park for the tenants who do not have park-facing views.
Where once this space was ignored and inaccessible, now residents can connect to their courtyard, as their movement through the building directly affects the projected image.
