The attached animated gif was created just for fun and was inspired by
Simon's "Simple White Sphere"
It has only eight cyclical frames.  Since the code is REALLY short, I've
decided to just include it here:

camera { location <0,0,-40> direction <0, 0, .89> up <0, 1, 0>
    right  x*image_width/image_height look_at <0,0,0>}

light_source{<-3,9,-30>color.5}light_source {< 3,-9, -30>color .5}

#declare PA=.0003*clock; #while (PA<pi*9)
   sphere{<0,0,0>,.15
   texture{pigment{color rgb<
      .2+.8*abs(cos(PA*24)),
      .2+.8*abs(sin(PA*18)),
      .3+.5*abs(sin(PA*36+pi/3))+.5*abs(cos(PA*36-pi/3))>}
      finish{ambient .3 diffuse .55 reflection .25
      phong .9 phong_size 20} scale 1/6 }
   translate <10*sin(PA*12),10*sin(PA*11.999),10*sin(PA*12.001)>
   rotate<360*sin(PA*18),360*sin(PA*35.99975),360*cos(PA*.02)> }
#declare PA=PA+.0003; #end

Wow, me likie.

You know, we should have a short code competition for animations. :-)

Maybe up the code limit, perhaps to 512 characters?

You know you've been raytracing too long when your wife's raytraced 
image you made to flatter her is the only one you see of her anymore.

Wow, that's rather impressive! so much nicer than mine :) and it has a nice 
organic feel to it while mine was a bit clinical...

Thanks for the mention. I'm going through what I imagine are the standard 
learning things - rollercoaster, terrains, etc... But once I've got the hang 
of the language, I'd like to come back to more surreal stuff.

Hi,

I'm still learning but always enjoy a challenge - Compact code is a good one 
(and usually teaches you new syntax) so certainly count me in!

Regards,
Simon

Thanks to William and Simon for the positive feedback.

As for the animation 512 character short code contest, two things:

1. How about if we just make it a "challenge" without formal rules or
judging and just let people post away?

2. Here's "Complicated Multicolor Sphere" crunched down to an entry:
(498 characters)
==================================================================
camera{location z*-40 direction<0,0,.89>right

Ooh, wow, people are already picking up on the idea. :-)

I'm not sure if 512 characters is too lax a limit or not. It seems like 
there should be a higher limit than for the still images, but doubling 
the limit might be too much. Hmm.

I should look into getting something together on Meetsoup...after I get 
my schoolwork a little more under control...and after I get my computer 
fixed. :-P

You know you've been raytracing too long when you find yourself 
daydreaming for hours on end what it would be like to go back in time 
and give Michealangelo a decent raytracer.

Now that you mention it, Mike's animation makes me think of the inside 
of a living cell.

He made his job easier by having a single, looping, continuous motion. 
For your image, you would need to go back and have the zooming motions 
start and stop gradually. The rotating motion of the structure makes the 
start/stop less noticeable, but we still perceive it at an almost 
subconscious level.

Long, long ago, I dumped some macros for smooth motion either under 
p.b.scene-files or similar. I'm not sure where anymore, and the file 
isn't on my computer now. :-) I could take a stab at recreating it; the 
math was pretty simple.

You know you've been raytracing too long when you look at real clouds 
and criticise their media and radiosity settings.

The one I did actually uses a cos curve to scale it - it makes a 1x1 cube, 
the scales it by cos(2*pi*clock)+1 meaning we get a scale from 0 to 2 (by 
scale, I#m referring to ball placement, not whole object scale) In theory, 
mine _should_ loop nicely - it's just lots of frames so can't be posted 
easily... (and assuming I posted the right one of course.... :D)

As for the short code contest. If only; I think a scene is short if it has
only one include file :-)

Thanks.  In the "small word" category, it's funny that you should mention
Dame Barabara in that I am lucky enough to have one of her works (Summer
Dance) on display not too far from me in the Meijer Sculpture Gardens in
Grand Rapids, Michigan.  There her work appears in the company of the likes
of Rodin, Henry Moore, Lipchitz and Oldenberg, among others.  I have often
thought about how neat it would be to be able to integrate POV-Ray's CSG
capabilities with one of those prototype "printers" that solidify liquid
plastic with scanning lasers for the purpose of producing fine art
sculpture.  ...Any skilled grant writers out there? ;-)

Best Regards to All,
