This work questions the significance of code in relation to its output, to the perceptible. How can we grasp their correlation? Which is the relevance of the manufacturing method when it is not shown in the product? What is the value of the non-visible? Does the tension between visible algorithm as a program and invisible algorithm inside the produced black square change the subjective view?

The video shows a sequence of screenshots. These present in the programming language processing various algorithms for the creation of an identical image: a black square on a neutral gray,as used in computer applications. The first algorithm consists of three lines of code and shows the simplest and most common way to do this. More complex, peculiar or abstruse algorithms, different programming techniques, built-in functions, points, lines and shapes follow to end up in the same visual output.
