   What about a viewmaster or an regualar stereoscope? I assume you see real   
   things as 3d.   
      
   Does this one work for you?

   Somebody long ago posted this program that takes a file with depth info   
   and makes a random ascii 3d out of it. Funny thing it worked for me on   
   unix (aix/freebsd/linux) but not on windows (turboc in a command window).   
   I never really tried to figure our why. It may have even been the DOS   
   font.

   #define COLS    79   
   #define COLS   120

        char m[COLS+1],s[COLS+1];   
        int i,e,c;   
      
        /* seed random number generator */   
        time (&now);   
        srand (now);   
      
        /* print fusion X's */   
        for (col = 0; COLS - col >= DEPTH0; col += DEPTH0)   
           {   
           for (i = 0; i < DEPTH0-1; ++i)   
              putchar (' ');
