Thanks I'm running a render on my old dual core laptop. with the default 
values and samples 10 and aperture 0.400.
It is rendering at 8 pps 2 hours into it an 17% done.

I'll try variance = 1/64 next.

Jim, she's ~929 units tall; try this with my version of the mesh to make her ~5
units tall:

camera {
   location <0, 0, -15>
   look_at  <0, 0, 0>
   right    x*image_width/image_height
   angle    60
}

light_source{ <-300, 300, -300> rgb 1 }

#include "shapes.inc"
#include "Lucy_POV_geom.inc"

#declare Lucy_Statue = object {
   Center_Object(Lucy_Statue, x+y+z)
   scale 1/929*5
   rotate y*180
}
object { Lucy_Statue pigment { rgb 1 } }

Cheers,
Rob

Ok ... here's my version rendered with RC4. I've settled for a more
subtle effect

Nice image have you tried using a back light?

I think that Jim gets first dabs 'cause he writes the documentation.

not until now I hadn't ... ran a low samples example (light source and
hdr flipped y*180) ... interesting effect, however looks like I'll need
a whole different tune (reminds me of tuning IF stages in
transmitter/receivers) ... maybe it's telling me that my settings
weren't so hot to begin with. The translucency effect is more
pronounced, almost to the point of practically being able to see through
the material. I can see that I have more experimenting ahead ... this
stuff is fun and frustrating at the same time ;-)

ha-ha ... and yikes this thread sure has generated a lot of bandwidth
(i'm posting 55th message to this thread)

Surprisingly, I find that full-spectrum light bulbs really do help.
