RG15. This piece starts from a solid 60 by 60cm wide and 30cm high. It is divided into four non-orthogonal parts. This element we get is hollowed and becomes our base piece - a simple element in wood, with 2cm thickness. From there, the user decides how many items to use, and how he wants to use them. The elements may be combined in innumerable ways, producing conformations that extend horizontally or develop vertically.
