Sway Object back and forth?

Unity Engine
1

I’m creating a List of game objects and I want to sway them back and forth randomly and slower than Mathf.PingPong allows. This is the code I have made so far and I am looking to sway each object in the list individually and to slow down the sway of Mathf.PingPong.

using UnityEngine;
using System.Collections;
using System.Collections.Generic;

public class GameObject: MonoBehaviour {


    public List<GameObject> gameList = new List<GameObject>(); 
    public GameObject goPrefab;
    private float listSize = 500.0f;

    private float time;

    void Start () {
        for (int i = 0; i < listSize; i++) { //andom.Range (0, 250)
            Vector3 startPosition = new Vector3(Random.Range (-45, 140), 13, Random.Range(-60, 60));
            GameObject rays = Instantiate(goPrefab, position, transform.rotation * Quaternion.Euler(0, 100, 100)) as GameObject;

            rays.transform.parent = transform;
            gameList.Add(rays);
        
        }

          }
    
    void Update () {

        time -= Time.deltaTime;

//Sway back and forth 
        transform.position = new Vector3(Mathf.PingPong(time, 1), transform.position.y, transform.position.x);

    }

You could possibly use a Hinge joint to gain the desired effect

Definitely not, they aren’t connected. They are just arbitrarily swaying in 3D space.

Can you use a tween?
