Hi,
  There's no way to do this in VMD itself, but if you exported the
scene to POV-Ray and then manually edited the scene file, you could
convince POV-Ray to render the intersection of your set of beads
using constructive solid geometry (CSG). That's probably the easiest
way to get such an image. You could also just write a Tcl script that
emits the beads to a POV-Ray scene file, that might be even easier than
taking the VMD output and then subsequently modifying it again...

Cheers,
