HP has added neat Easter egg in their MediaSmart Servers, called the LED Light Show. There are plenty of light shows to choose from for your pleasure. This is how you do it:

1. Go to Windows Home Server Console.
2. Click on ‘Settings’, top right corner.
3. Click on ‘MediaSmart Server’ tab on the left navigation.
4. Then go over to ‘LED’ tab.
5. Hold Shift, Ctrl, Alt and left click on the MediaSmart picture. And an Easter egg should appear next to it. From there you can choose what light show you want to see.
