The other object is a little harder to pin down - it's a union of several boxes
and a couple intersections (with bounded_by containers) comprising the Metallica
logo. It's very low-tech CSG originally made with POV-Ray version 1, but it has
bevelled edges and reflection. Depending on what other objects I include in the
scene, render times vary quite a bit when using radiosity. I'm trying to narrow
the problem down more...

Thanks for the advice regarding the sphere_sweep!
