A check digit is an authentication mechanism used to verify and validate the authenticity of a series of characters such as a single mistyped digit or a permutation of two successive digits, thus avoiding typing errors. The check digit of Chilean cars license plates is calculated using Modulus 11 and uses a conversion table to convert letters to numbers. The artist wrote an algorithm to calculate Modulus 11 and to render a color for the check digit. Starting with her license plate of the car, it calculates the next 124 numbers. If it finds a 10, it renders gold.

The artist converted the Fibonacci sequence to binary. Every binary number with eight digits was placed horizontally on a 3 x 3 matrix. The red cell was made to separate the first four digits from the last four. Every black cell represents a 1. The first two numbers on the top row are the ones that start the sequence.
