Mirror tricks
The picture shows what happens when you put just one ball in a kaleidoscope, which is the "double" of the kaleidoscope corresponding to the symmetry group of a dodecahedron: we see 60 balls, organized in rings of 6 balls (where two mirrors meet at an angle of 60°) or 5 balls (where two mirrors meet at an angle of 72°).
You can see an analogous photo in the same kaleidoscope; or the photo of an analogous situation in a different kaleidoscope.
From the exhibition Simmetria, giochi di specchi - Symmetry, playing with mirrors.
