How many balls?
The picture shows what happens when you put just one ball in a kaleidoscope, which corresponds to the symmetry group of a cube. The 48 balls that you can see correspond to the 48 elements of the symmetry group of the cube.
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.
