Maybe it's because I haven't yet had my morning coffee but I find his first example overly complicated. A much simpler and immediately obvious one [from this article](http://www.nyx.net/~gthompso/quine.htm):

     char*f="char*f=%c%s%c;main()
     {printf(f,34,f,34,10);}%c";
     main(){printf(f,34,f,34,10);}
