Exercise One

Create a world with the above shape in it using the Sony_Appearance PROTO to give it a description field and use the backface field so you can see both sides of the object without having to write two faces.

Exercise Two

Now, write a cube, but without two of the faces and give the cube the description "Hello world!" using the Sony_Appearance PROTO.

You should end up with a cube you can see both the inside and the outside having writen only four faces and when your mouse cursor crosses it, you should see Hello world! appear on or obove the object. Don't forget to turn the Scouter option on.
