The algorithms order random sequences of numbers in succession. They are executed in the lisp interpreter in the trace mode which allows to visualize the internal steps of the recursion.

Starting from the actual execution of the sorting algorithms the work develops along three lines: 1) Sorting: a color is assigned to each number so that the final sorted sequence has a well-terminated color scheme. 2) Dream: each dream is an image that is used to color the codes and steps of the recursion. The dream develops over time. At the beginning the dream is confused and the colors of the image are distributed with a component of randomness. This component decreases until the dream becomes clear and then fades away. 3) Narration: the work is accompanied by a synthetic voice that takes up the steps of the recursion, enunciates numbers, narrates the dreams and questions the human and/or artificial nature of the work.
