I made this representation of Pi to one thousand places out of Cuisenaire Rods, those wooden blocks that generations of schoolchildren used in maths class. Many of us preferred to build things with them than do actual maths. If I’d paid attention in class I would have found that Pi is used to calculate the area and circumference of circles. And as a number it goes 3.1415926535... and so on. My Pi chart starts at the top and runs left to right and down for its thousand digits. One problem I struck was how to represent zero (there are no zeroes in Cuisenaire) so I inset small mirrors to show spaces of emptiness.
Dimensions: approx 800mm in diameter. Materials: wooden blocks, acrylic mirror, timber baseboard.
