Simple but quite nice, I was planing to do quite simmilar iamge soon, but 
with few extra ideas :) Btw how is Your's radiosity count patch comming?

-- 
#macro g(U,V)(.4*abs(sin(9*sqrt(pow(x-U,2)+pow(y-V,2))))*pow(1-min(1,(sqrt(
pow(x-U,2)+pow(y-V,2))*.3)),2)+.9)#end#macro p(c)#if(c>1)#local l=mod(c,100
);g(2*div(l,10)-8,2*mod(l,10)-8)*p(div(c,100))#else 1#end#end light_source{
y 2}sphere{z*20 9pigment{function{p(26252423)*p(36455644)*p(66656463)}}}//M

Last time I was working on that small project...... that might be more than
a year ago? I don't remember anymore. All I know is that the distribution
was far from perfect, especially the amount of samples at the "edge" of the
hemisphere was too low --> artifacts!!!! I still would like to get in touch
with the guy who did the 1600 samples distribution.

Funny that he came into the same low-angle problem as I (and probably others
also) did.
