	private float time = 0;

	public static void main(String[] args) {
		new ColorBoxApp().start();
	}

	@Override
	public void simpleInitApp() {

		box = new Geometry("Box", b);
		Material mat = new Material(assetManager, "Common/MatDefs/Misc/Unshaded.j3md");
		box.setMaterial(mat);
		rootNode.attachChild(box);
	}

	@Override
	public void simpleUpdate(float tpf) {
		time += tpf;
		box.getMaterial().setColor("Color", new ColorRGBA((float)Math.abs(Math.sin(time)), 0, 1-(float)Math.abs(Math.sin(time)), 1));
	}
