As well as taking something from the environment to then modify and put back into the environment we need to make this seen by an audience. The 'something' in this case is projected onto an area of the 'Dance Academy' building and the audience in this case is the citizens of Plymouth.
We decided to do a small survey of peoples movements at the time (over 20min period at 1650 - 1710):
People at bus shelter/opposite restaurants = 12 people/1 bus
People walking by on foot = 55
People walking by side of building on foot = 8
Cars entering and exiting car park = 38 cars
Traffic passing on main road = 422 vehicles
^Drawing done by Jon.
So as you can see, a lot of cars passed and these are all potential viewers for our projection piece. There was also a lot of foot traffic and a fair amount of cars going into the car park, so more potential audiences through that!
