\section1 Setting the Scene
- When constructing the scene we first calculate some random offsets using the global qsand()
- and qrand() functions. We will use these offsets to scatter the initial position of new Cloud
- objects.

Next we place a text item in the center of the scene to represent the local device and
surround it with four concentric circles to help visualize the orbits.
