Himmeli consists of two objects that are three-dimensional “shadows” of the same four-dimensional object called the 24-cell. The shape of this kind of shadow (projection) depends on the vantage point from which you are looking at it.

The bigger object is a three-dimensional Schlegel diagram that is made of aluminium tubes and inspired by a traditional Finnish Christmas decoration object, himmeli. The smaller object is a stereographic projection where an attached lamp creates two-dimensional shadows on the walls. The object is made of bent copper tubes that are connected with 3D-printed plastic pieces.

The work originates from a cross-disciplinary course Crystal Flowers in Halls of Mirrors: Mathematics meets Art and Architecture held in Aalto University.
