easy to color, shade, texture as well
assigning materials
what is a Material inside of Unity?
A shader and its associated settings
Textures

Unity’s Standard Shader attempts to light objects in a “physically-accurate” way. This technique is called Physically-Based Rendering or PBR for short. Instead of defining how an object looks in one lighting environment, you specify the properties of the object (e.g. how metal or plastic it is)
implement head lotation
using UnityEngine;
using System.Collections;
public class HeadRotation : MonoBehaviour {
void Start(){
Input.gyro.enabled = true;
}
void Update(){
Quaternion att = Input.gyro.attitude;
att = Quaternion.Euler(90f, 0f, 0f) * new Quaternion(att.x, att.y, -att.z, -att.w);
transform.rotation = att;
}
}
