Each work is preceded by its construction scheme. Each work is also identified by a four digits number: the first digit refers to the first level starting from the top, the second digit refers to the second level and so on. The number "zero" corresponds to the absence of the section while the number "one" corresponds to the presence of the section. The shadow applied on the works has an angle of forty-five degrees. I hope you are going to like it and thank you for watching.
