A small stellated dodecahedron: the faces are 5-pointed stars and there are 5 of them around each vertex. It can be reproduced between the mirrors in the kaleidoscope relative to the group of symmetry of the dodecahedron.
This image has been used in the posters on polyhedra realized for the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors.

The image belongs to the sections...:
The symmetry group of the dodecahedron (*532) (Symmetry)
Star polyhedra (3D geometry)
Posters about polyhedra (From the exhibitions of matematita)
