Not just possible, it happened. I have personally rendered the file
he created.

it is not connected with the thread but I observe your signature and I wait for
Warp's reaction to your wasted space. But there is no reaction. So, allow me to
reduce your signature a little :-)
#macro c()union{cylinder{x+y/2x.1}difference{torus{.5,.1rotate 90*x}box{x+z/5

that's probably not everything I can do but perhaps now Warp could start :-)

Well, I think I can beat that:

x*X}#end #macro C(A)cylinder{A,A-y*.5.1}#end merge{c(.5)c(-.5)C(x)C(-x)C(0)

Ok, the texture is not identical to the original, but I don't think it
matters that much.

Everybody around here whines about how important it is to use proper
indenting yet look at that mess! When I do it people critisie me. When
you guys do it in your sigs it is all of a sudden ok. Talk about double
standards!

and depending on just how unimportant the exact texture is, the rotate 90 could
be changed to rotate 9 or removed altogether (and the translate z*2 could be
moved to the end, which would also change the texture.)

I agree.
//// New, improved and FAIR code follows ////
#macro c (X)

Perhaps your scripts should create more signaturing results. For example try
this:
#warning#macro P(S)#local T=val(substr(S,1,7));#local B=substr(S,8,strlen(S)-7)
#local O=M(T)#if(strlen(B)>0)#local O=concat(O,P(B))#end O#end#macro M(V)#local
S=chr(mod(V,123))#local F=div(V,123);#if(F>0)#local S=concat(S,M(F));#end S#end
P("167668818409731737237048969510822381537545154019204883010625882")

Same reason you (might) render Schroedinger's cat even though
the box is closed: more complete simulation of reality! ;)

It is my goal in life to create a simulation of reality that is
indistinguishable from reality, we can insert the simulated reality and
noone would be the wiser because it would be *exactly* the same... or
perhaps I already have ;)
