....but it won't be today.

(but I can get rid of F if I find a different seed for the same sequence, but
whose next value is 2, not 1 - that'll have to wait for tonight)

Heh, spent awhile with #macro H()#local#end and couldn't figure out why it
didn't work - doh.

#macro H()#declare#end#macro A(B,C)cone{0,0y.1rotate z*C*-90pigment{rgb D/6}
translate B}#end H()D=<-2,1,6>;H()E=seed(20960);H()F=11;#while(F)H()G=int(3*
rand(E));A(D,G)H()D=D+<1-abs(G-1),1-G,0>;H()F=F-1;#end light_source{1,1}//TM

pigment{rgb<1-C/8R/2C/8>}}#local V=V-128/B;#end#local B=B*2;#local C=C+1;#

You will have to find a new appropriate seed for this version but apart
from that...:

light_source{1,1}#macro R(D,F,G,E)cone{0,0y.1rotate-90*z*G 
pigment{rgb D/6}translate D}#if(F)R(D+<1-abs(G-1),1-G,0>,F-
1,int(3*rand(E)),E)#end#end R(<-2,1,6>,10,2,seed(20960))//TM

Did you clean it in a hot wash? ;)

I thought I will not make it shorter just to make Tom Melly happy but I
couldn't resist ;-)

light_source{1on}#macro R(D,F,G,E)cone{D,0D+vrotate(y,-
90*z*G).1pigment{rgb D/6}}#if(F)R(D+<1-abs(G-1)1-G,0>F-
1int(3*rand(E))E)#end#end R(<-2,1,6>10,2seed(20960))//TM

Hmm, also seems to have lost something - however, gah!, I had it in my head that
vrotate required an include. Doh!

It is never short enough:

light_source{1on}#macro R(D,H,F,C)cone{D,0H.1pigment{rgb D/6}}#if(F)R(H
H+vrotate(y,-90*z*int(3*rand(C)))F-1C)#end#end R(<-2on,6><-2no

... or correct enough? Everyone seems to be duplicating the same mistake - the

is going on, I'll find a new seed.
