Attached a couple images showing modes 2 and 3 of clipped_by{}.

The core SDL looking like:

#declare OO = object {
     sphere { 0, 0.5
         texture          { pigment {Green} normal { micro 0.5 } }
         interior_texture { pigment {Red}   normal { micro 0.5 } }
     }
     bounded_by { mode 1
                  sphere { <+0.3,+0.0,+0.0>, 0.25 }
                  sphere { <-0.3,+0.0,+0.0>, 0.25 }
                  sphere { <+0.0,+0.3,+0.0>, 0.25 }
                  sphere { <+0.0,-0.3,+0.0>, 0.25 }
                  sphere { <+0.0,+0.0,+0.3>, 0.25 }
                  sphere { <+0.0,+0.0,-0.3>, 0.25 }
     }
     clipped_by { mode 3
                  sphere { <+0.3,+0.0,+0.0>, 0.25 }
                  sphere { <-0.3,+0.0,+0.0>, 0.25 }
                  sphere { <+0.0,+0.3,+0.0>, 0.25 }
                  sphere { <+0.0,-0.3,+0.0>, 0.25 }
                  sphere { <+0.0,+0.0,+0.3>, 0.25 }
                  sphere { <+0.0,+0.0,-0.3>, 0.25 }
     }
     // Or: clipped_by { mode 3 bounded_by }
}
