 ## Example
 Here's an example that illustrates the basic usage of this api:
 ```java
+import java.awt.Color;
 import jimbo.pijava.blinkt.BlinktController;
 
-public class BlinktTest {
+public class BlinktExample {
 
 	public static void main(String[] args) throws InterruptedException {
-		BlinktController blinkt = new BlinktController(); //create the controller
+		System.out.println("Starting demo"); //the VM can take some time to load on the pi so we print a nice little heads up that we're starting
+
+		BlinktController blinkt = new BlinktController(); //create te controller
 		blinkt.setBrightness(.1F); //we don't want to blind ourselves
 
-		int i = 0;
+		boolean movingForward = true;
+		int i = 1;
+
 		while (true) {
 			blinkt.clear(); //clear any previous state
-			blinkt.set(i, 0, 255, 0); //set LED number 'i' to green
-			blinkt.push(); //push the new state to the blinkt
 
-			i++;
-			if (i > 7) i = 0;
+			blinkt.set(i-1, Color.RED); //set the left pixel to red
+			blinkt.set(i, 0, 255, 0); //set the middle pixel to green
+			blinkt.set(i+1, Color.BLUE, 1); //set the  last pixel to blue with full brightness
+
+			blinkt.push(); //push state to the GPIO pins
+
+			//Some back and forth controlling
+			if (movingForward) i++;
+			else i--;
+
+			if (i >= 7) {
+				i = 5;
+				movingForward = false;
+			} else if (i <= 0) {
+				i = 2;
+				movingForward = true;
+			}
 
-			Thread.sleep(500);
+			Thread.sleep(250);
 		}
