Hi All,

I have successfully created first iteration of a menger sponge by using this nested loop

```
for (int x = -1; x < 2; x++) {
for (int y = -1; y < 2; y++) {
for (int z = -1; z < 2; z++) {
int sum = abs(x) + abs(y) + abs(z);
int r = 100;
if (sum >1) {
box.setPosition(x+x*r,y+y*r,z+z*r);
box.set(100);
ofSetColor(255/sum, 255/sum, 255/sum);
box.draw();
}
}
}
}
```

My question is how would I proceed to second iteration from here?

```
#ofApp.h
ofBoxPrimitive box;
```

Thanks in advance
