The presented modular structure, consists of cylinders that vary in radius according to the overall curvature of the surface shape. Considerations such as orientation, height and sub-function govern the radius of these cylinders as well. This geometry provides a stage that is parametric, with the ability of modifying the orientation of the units to best suit di rent themes of exhibitions. It can perform as a background for the exhibited items or can also contain them, o ering special lighting atmosphere to the space.
