Here's a version with radiosity and HDR. Like I said the metallic effect
requires a light source, so this needed a bit of tweaking to make the light
source match up to roughly the position of the sun in the HDR image without
interfering too much with the radiosity. I also turned off the sharp specular
highlight that was on the gloss coating 'cause it's not needed with such a
realistic reflection image.

Basically it looks good if most of your lighting comes from light sources, if it
doesn't then you'll need to mess around creating some lights just for this
object. But that's what I did here and I think it's worth the effort.

And while we're on the subject, does anyone know if it's theoretically possible
to get specular radiosity interaction? I know pov can't do it, but as far as I
can see it should be possible to do a specular calculation on the radisoity
samples. It would be slow but still much better than true blurred reflections.
