public class Temp : MonoBehaviour {

	void Start () {
		StartCoroutine (this.TakeScreenShot ());
	}

	IEnumerator TakeScreenShot(){
		// Screenshot を撮る
		string path = Application.dataPath + "/screenshot.png";
		Application.CaptureScreenshot(path);
		Debug.Log("path:"+path);

		// 即座に保存されるわけではないので待ち
		while(!System.IO.File.Exists(path)){
			print ("Saving");
			yield return null;    
		}
		
		// スクリーンショットの読み込み
		byte[] image = File.ReadAllBytes(path);
		
		// Texture2D を作成して読み込み
		Texture2D tex = new Texture2D(0, 0);
		tex.LoadImage(image);
		
		GameObject.Find ("Cube").GetComponent<Renderer> ().material.mainTexture = tex;
