I want to separately distance the square frames on Z axis by nearing the green sphere. These are mirrored on z axis, multiplied in the same collection, no array. I've found [similar effects here](https://youtu.be/k5HhYzd1LjM)

Should I just put them as instances on circled grid or is there an option with just setting a position in geometry nodes?
