There are over 500 apps included with the Magic Carpet system. Each app has a theme that it is built from. For example, take the app "Poppies". This app is built using the "Scatter" theme which is based around a background image, several foreground images which can be "scattered" around, and a background sound track. There are 35 themes that make up the numerous apps on the system.
You may create your own version of these apps using any of the 35 themes available, which for the purposes of creation, are known as "Templates".
Let's just go ahead and make an app. It's really very easy. After following this tutorial you will be able to easily use any of the other templates to create an app.
