Dodecahedron – (Tewlve field-solid)

A regular twelve field-solid, consisting of a kaleidocycle with 18 pieces (this is a turning inside-out ‘solid’ of tetrahedra) and 2 bolts, which surrounds a stellated tetrahedron (Stella Octangula). It can be transformed into various forms in space and last but not least, you can put it together into a real pentagondodecahedron.
