Hello, I made this sketch  
[Link to sketch](https://editor.p5js.org/lunalcampbell/sketches/wkZCkSJ6_)  
as you can see its a cube made of smaller cubes that expand and retract using sin.  
My problem is that the smaller cubes expand and retract from the corner cube and not from the center cube.

Your initial translation needs to be relative to the currently calculated gap:

```auto
  translate(-(gap + 40) * 4.5, -(gap + 40) * 4.5, -(gap + 40) * 4.5);

```
