Thirty-one Labyrinths for December is a series of labyrinths in which the day of the week and its number dictate a set of rules to create two drawings: a plan and a perspective. Each labyrinth is drawn within a grid of 31 by 31 squares. The day of the week determines the number of blue points one needs to collect before heading to the exit (Monday is 1, Sunday is 7). 

The day number determines the amount of right or left decisions one needs to make to find the exit (decisions are drawn as small blue dots). If a weekday, points are found inside the walls; if a weekend, points are found in open areas and the forest. While the plan introduces the entirety of the labyrinth and the same view as the one who designed it, the perspective appears as a three-dimensional representation of the entrance, that first encounter between the one who solves and the labyrinth.
