The little rectangles are the windows of the houses, correct?

Would u mind explaining what is void showSkyscaper() ?  
I have edited to this.

String storey = “”;  
int[] tokens= {}; // split(storey, “,”);

void setup() {  
size(1000, 1000);  
background (0);  
}

void draw() {  
textSize(25);  
String caret ="";  
if (millis() % 1000\<200) {  
caret="|";  
}  
fill(255);  
rect (0, 0, 1000, 40);  
fill(0);  
text( storey + caret, 0, 30);

textSize(15);  
fill(255);  
text(“Please enter your number from 1 to 10. Maximum input is 5.”, 250, 60);

for (int i = 0; i\<tokens.length; i++) {  
fill(211, 211, 211);  
noStroke();  
rect(i \* 200, 1000-tokens[i]\*80, 200, tokens[i]\*80);

```
for (int y=0; y < 20-1; y++) {
  for (int z=0; z < tokens[i]*80; z+=30) {
    // int a = (int) random(1);
    if (random(2) < 0.5 ) {
      fill(0, 0, 255);//blue
    } 
    else {
      fill(255);
    }
    rect((i * 200)+(y*10)+9, height -z, 
      5, 10);
  }
}

```

}  
}

void keyTyped() {  
if (key == BACKSPACE) {  
if (storey.length()\>0) {  
storey = storey.substring(0, storey.length()-1);  
}  
} else if (key == ENTER) {  
// We submit when the user presses enter  
tokens = (int[]) append (tokens, int(storey));  
// reset  
storey="";  
} else if (key\>=‘0’ && key \<= ‘9’) {  
storey += key;  
}  
else if (key==‘n’){ //night mode

you really should learn how to post code.

showSkyscaper() is a new function that I defined. I call it when a new skyscraper is made (with Enter in keypressed). It shows the windows in one (the new) skyscraper.
