BIG numbers from a little LCD

I won't go through all the LCD stuff (mine is a little customized), but here are the important bits (don't have a fancy formatter yet):

//create some strings to index into for displaying the big numbers
//                      0         1        2        3        4          5         6       7         8         9
char bignumchars1[]={4,1,4,0, 1,4,32,0, 3,3,4,0, 1,3,4,0, 4,2,4,0,   4,3,3,0, 4,3,3,0, 1,1,4,0,   4,3,4,0, 4,3,4,0};
char bignumchars2[]={4,2,4,0, 2,4,2,0,  4,2,2,0, 2,2,4,0, 32,32,4,0, 2,2,4,0, 4,2,4,0, 32,32,4,0, 4,2,4,0, 2,2,4,0}; 

...
//cycle through printing out 0 to 9
void loop (void){     
  for(int x = 0;x<10;x++){
    lcd.gotoXY(0,0);
    lcd.print(bignumchars1+x*4);
    lcd.gotoXY(0,1);
    lcd.print(bignumchars2+x*4);
    delay(1000);
  }
}     
...

void setup (void){   
...
//creating the custom fonts:
  LcdCommandWrite(B01001000);  // set cgram
  byte chars[]={
    B11111,B00000,B11111,B11111,B00000,
    B11111,B00000,B11111,B11111,B00000,
    B00000,B00000,B00000,B11111,B00000,
    B00000,B00000,B00000,B11111,B00000,
    B00000,B00000,B00000,B11111,B00000,
    B00000,B00000,B00000,B11111,B01110,
    B00000,B11111,B11111,B11111,B01110,
    B00000,B11111,B11111,B11111,B01110};
        
    for(byte x=0;x<5;x++)      
      for(byte y=0;y<8;y++)      
          LcdDataWrite(chars[y*5+x]); //write the character data to the character generator ram     
...
}

Course the technique isn't limited to numbers, or a 3x2 character box, or 16x2 LCDs.
