Once that's done, what's to stop you from modifying the source code instead of printing it verbatim, slowly shifting forms as you iterate on each successive output? Naturally, you'll want to make a game that's played in its own source code (click for an animation): #include<stdio.h> #define z else #define y return #define x int #define w if( #define v putchar( #define B v 10); #define A v 92); /* IOCCC29, w = up, e = down */ x a= 32 ; x b= 6 ; x c= -1 ; x d= 1 ; x e= 5 ; x f= 10 ; x g= 62 ; x h= 5 ; x i[6]={ 1,3,1,4,1,0} ; char*j[]={ "\ \ #include<stdio.h>'#define$z$else'#define$y$return'#define$x$int'#defin\ e$w$if('#define$v$putchar('#define$B$v$10);'#define$A$v$92);''/*$IOCCC\ 29,$w$=$up,$e$=$down$*/''x$a=","32",";x$b=","6",";x$c=","-1",";x$d=","\ 1",";x$e=","5",";x$f=","10",";x$g=","62",";x$h=","5",";x$i[6]={1,3,1,4\ ,1,0};char*j[]={","","};x$k=0;x$l=1;x$m(){l++;w$l==1)y!v$44);w$l==2)y!\ v$34) ;char$o=j[k][l-3];w!o){l=0;k++;y!v$34);}w$o==34){A$y$v $34);\ }w$o= =92){A$y$A}w$o!=32&&o!=1 0)y!v$o);y$m();}void$n(x$o, x$p){\ aspri ntf(j+o,\"%i\",p);}x$mai n(x$o,char**p){char*q;w$c<2 )a+=c\ ;b+=d ;x$r=b+2>f/2&&b<f/2+5;x$s=a+2==g&&b+2>h&&b<h+5;w$c<2){ w$a==\ e+2&& r||s){a-=c;b-=d;c=-c;}w$a<0||a>67){w$a<0){c=2;d=0;}a=3 4;b=6\ ;}w$b<0||b>13){b-=d;d=-d;}w$f/2>10)f-=2;w$h>10)h--;w$o>1){w*p[1]==119&\ &h>0)h--;w*p[1]==101&&h<10)h++;}s=f/2-b+1;w$s<0)f++;w$s>0)f--;}z{b++;w\ $d<0)d++;w$b>=13){w$o>1&&*p[1]==119)d=-4;b=13;}w$f/2<15-i[c-2])f+=2;z$\ e--;w$h<15-i[c-1])h++;z$g--;w$e+3<=0){c++;w$c<7){e=g;f=h*2;g=70;h=15-i\ [c-1];}z{e=5;g=62;c=1;d=1;}}w$a+2==e&&r||s){c=2;e=5;f=28;g=62;h=12;}}n\ \ (1,a);n(3,b);n(5,c);n(7,d);n(9,e);n(11,f);n(13,g);n(15,h);for(s=0;s<","29",";s++){w$s)v$32);q=j[s];r=1;for(char*t=q;*t;t++)w*t==","36",")v$32);z$w*t==","39",")B$z$w*t!=32&&*t!=10){r=0;v*t);w*t==123||*t==125||*t
