Interesting date on that Max Newman paper - 2nd September 1942. Newman started working at Bletchley Park on 31st August, where he was deeply involved in the decryption of the Lorenz cipher and the development of Colossus.

I like this Python3 quine, which doesn't use repr printing:

  (lambda s,q,b,k,c,e:print(b+s+k+b+q+s+q+c+q+e+q+q+c+q+b+q+c+q+k+q+c+q+c+q+c+q+e+e+q+k))("lambda s,q,b,k,c,e:print(b+s+k+b+q+s+q+c+q+e+q+q+c+q+b+q+c+q+k+q+c+q+c+q+c+q+e+e+q+k)","\"","(",")",",","\\")

If you don't like those hard-coded character constants, lack of newlines, and compiler warnings, here's a C quine on similar lines:

  #include<stdio.h>
  int main(){
    char q='"',n='\n',b='\\';
    char*f="#include<stdio.h>%cint main(){%c  char q='%c',n='%cn',b='%c%c';%c  char*f=%c%s%c;%c  printf(f,n,n,q,b,b,b,n,q,f,q,n,n,n);%c}%c";
    printf(f,n,n,q,b,b,b,n,q,f,q,n,n,n);
  }

VRML is still used as an input format for colour 3d printing, eg. https://www.stratasysdirect.com/resources/design-guidelines/...

How about a 3d model of the universe, inverted, say, in the (model) earth's surface?
