Wow... you did this with ... *boxes* ... Impressive!

Wait - there's a contest for "few code, many objects"?
Man, imagine if you could describe POV-Ray scenes in Haskell... >:-D

Actually, SDL is powerful enough to implement Ackermann's function,
which means that with *very* little code you can create so many
objects that it will quickly overwhelm all CPU power and memory in
the world combined. (Ah, the joys of recursion...!)
Of course, the *usefulness* of such a thing is questionable, so I've
chosen to interpret the contest as "with as little code as possible,
create as many objects as possible that would result in a
_meaningful scene_".

Beatiful picture, IMO. It never ever dawned on me to put light sources
inside a routine, thanks for the idea.

I've done it before, but it tends to overwhelm the scene if you're not
careful.
Here, it came out great :)

Very very nice - I actually got vertigo looking down that tunnel...

Great effect, the image would look even better with a bit of focal blur but
I guess with that many light sources and objects you would need all the
computers in the world to render it... How long did the render take?

About one and half minute, few time... I haven't enought pacience to wait a
slow render (more than 5 minutes)
My computer is a AMD Athon 2000 with 384 RAM and w2000 SP4 server
I will try render with focal blur

Here's mine. I could've bumped it up and squeezed more cubes into each ring,
but I'm not a CPU sadist. 2 minutes 30 seconds at 800x600 with 0.1
antialiasing
//Lots of objects in little code
#macro circ (a)
#declare i = 25;
object {
union {
#while (i>0)
box {-.07,.07
pigment { color rgb .5 }
translate 1*z
rotate i*(360/25)*y
}
#declare i = i-1;
#end
#if (mod(a,10)=0)
light_source {<0,0,2>
color rgb <.2,.2,.6>
}
light_source {<0,0,0>
color rgb <.2,.6,.2>
}
#end
}
translate (a/8)*x + 2*z
rotate (360/40)*a*x
}
#end
#declare j = 140;
#while (j>=-140)

(yes I use MegaPOV, I never bother switching back and forth since MegaPOV is
fully back-compatible)
I think this is an elementary example of how powerful lightsources are. As
you can see, there are only 58 lightsources in a scene full of thousands of
boxes and it looks fully lit.
