messing around with a blender torus knot plug-in ... i tried several 
other materials (wood, metal, ceramic) but the glass looked best. the 
ground plane has waves for now ... facets ain't bad either!

I like this. I especially like the red of the torus knot. Although I 
wonder if max_trace_level should be a bit higher.

Complex and sophisticated! Very nice.

I kind of wish it were a little brighter, though; then I could clearly see all
the wonderful details.

The red of the glass is fascinating and attractive.

Like Stephen suggested, there are some small artefacts still visible.

I'm always leery of .png images and how they show up in web browsers (a legacy
of the past, I guess; can't shake that feeling.) As your post looks a bit dark
on my end, I was wondering if I'm seeing what you see. Of course, the look may
be just as you intended; but here's a screenshot (as seen in latest Firefox on
my Windows XP machine) and saved as a .jpeg.

i've got a wee bit of normal on the glass ... maybe that's it 
(max_trace_level already at it's upper limit 256)

hmmm ... thanks for the feedback on darkness you guy's. i'm fooling 
around with a back-lit approach and obviously it still needs help. one 
thing i /did/ change this morning was to bump up the fade_distance on 
the glass material. where i'd like to end up with this is glass that has 
some zing to it while muting the background ... maybe a fools errand :-)

btw: the screen shot doesn't look overly dark to me

here's a much better rendition ... changed hdr background and aligned 
the sun in the image with the key light. changing fade_distance on the 
glass helped some, but ended up having to add a fill light 180 and much 
lower than the key light, it's also (the fill light) the same color as 
the glass. i also added photons (excluded the fill light) ... oh and 
removed the normal from the glass

It looks as dark to me than the original. I wonder if it have anything 
to do with my CTR monitor compared to the LCD ones... My display gamma 
is at about 2.5. If I increase the brightness to correctly see the 
image, my text becomes all blury.

could be ... it looks the same in preview window, gwenview, gimp, t-bird 
(this post) and f-fox (on my blog) ... sometime ago i went through all 
the gymnastics of getting my display calibrated (gamma-wise) so i'm at a 
loss. since the object is back-lit you'd expect the foreground to be 
dark-ish right?
