Never mind, that wasn't it.  Or at least not all of it.  This is the same
file (with the <8,0,0> inside_vector) but the torus is off, and the camera
has been moved from <5,19,11>*3/2 to <5,11,19>/2.  Notice the odd ghosts on
the hole on the right, and sides on the upper holes with the lights
shining across them (through holes on the other side of the band).
