To me it does not appear to be existing behind the surface of my monitor. For
your image to appear as such, the margin of the image would have to be
partially shaded, as if the case of the monitor itself were casting a shadow
onto the objects below.

Your image by itself is very nice. I do like your abstract images.

But...

24 hours is a long time for a render to complete. By using Rune's illusion.inc,
you can save a *lot* of render time by projecting a pre-rendered image to the
existing geometry and re-rendering the scene with focal blur. The results are
not entirely accurate, but for an image such as this, the artifacts would not be
readily visible.

I wish POV-Ray could natively support projection images so this process would be
easier. As it is now, to avoid gamma issues, I have been using a patched version
of illusion.inc which supports .hdr images.

Anyway, nice image, and I don't think your excessive use of focal blur is bad at
all.

Sam
