    You can get POV to render the background as transparent. Put
Output_Alpha=true into your POVRAY.INI or use the +UA command line
parameter. Oh, and you'll need to use an output file format that supports
transparency (.png or .tga) - this can be set, again in POVRAY.INI, using
Output_File_Type=N for .png or =T for .tga, or use the command line
parameters +FN (.png) or +FT (.tga)...
    See section 5.2.2.3.1 of the POV help file for more info on output file
types and transparency...

    Oh, and I've never tried this, but my guess would be, if you want, say,
50% transparency you could put background { colour rgbt <1,1,1,0.5> } in
your scene file... Can anyone confirm that ??

background essentially doesn't exist, I guess you could say. It's not a
object so maybe that's the logic. So the obvious: putting a backdrop plane
is a possible workaround. Use pigment {rgbt 0.5}, rgbf includes the color
value in the transparency and so isn't reliable for exact percentage. You'll
also need to set finish {ambient 0 diffuse 0} to prevent any color intensity
shifts due to light sources shining onto it.

Oh yeah, I like that stasis chamber too. Needs a squid-like creature inside
;-) Also some erratic electrical arcs crossing from the bottom unit to the
upper just for effect.

Now, that doesn't work either.  It just turns out dark grey... but I finally
got the effect I wanted by cutting it into pieces in photoshop and setting
opacity on the layers.
