This is how the Pi Project appeared at the North Bank Gallery in May 2015. Installing the work took many hours and many trips up and down the ladder. Opening night brought in a crowd of over 300 people, with many taking their own pictures from various angles, including laying flat on the floor and shooting straight up.
The ribbon started in a back corner with the number 3 and ended up in the front window with the last available digits. Almost every number was visible from some angle.
Additionally, 8 pies were offered (and disappeared quickly).
