Who wants a challenge in making an image?

Here it is: make a scene containing as many of POV-Ray's features as
possible and post it in a reply to this thread.

Anyone interested?

Rohan:

Maybe a better challenge would be along the lines of:

Make an image that consists of only 36 spheres and no
CSG.  Who makes the most visually interesting image?

The problem with using as many features as possible is that
the rendering time would at some point approach infinity, even on a relatively
speedy PC.  Isosurfaces, photons, radiosity, area lights, focal blur, etc.
all in one scene?  Yeek ...

I might participate in another type of challenge.

I've done that, it took a week to render 7 lines at 800x335, and then my
machine crashed because I was playing a game during the render :-P

Okay, so maybe using all those really slow features isn't such a good idea.

How about I change it to this:

Make a scene using as many of POV-Ray's features as possible, and takes
under 3 hours to render on a P3/500 (which is how long benchmark.pov takes)
at 800*600.

How does that sound?

My current scene is just like that. Considering the amount of CPU
power I have at my hands now*, it shouldn't be a problem :)

What I see as a problem though is making it visually appealing

*3 2x2.4 P4 7 2GB each as a server + about 10 workstations at 1.4+ GHz
each (and a few slower laptops).

You should impose a theme, like "bedroom of a child", or you will end up
this a collection of objects with no relation and no reason.

You should as well concatenate the portefolio scenes in a single image...

Nice!  My setup is ... erm ... uh ... well, I'd better not say, or else I'll
look stupid.  Let's just say that a relatively simple isosurfaces rendering
took 5 hours and 20 minutes the other day.  Still, it's quite an improvement
over my old 486.

My PC is rendering...
I couldn't wait for a week so I made a little low-quality preview on my 
second machine. Here it has no photons, no media, no anti aliasing, no 
area lights, fast radiosity settings and poor focal blur settings. Took 
18 hours (!!) to render on a celeron 500 (running a linux povray 3.5 not 
compiled on the machine - I suppose it would be much faster on a windows)
The final higher quality version should come in a few days (thanks to my 
athlon XP :-)
As usual, Questions, comments ?
