How to set up a randomising function

A couple of sections on arbitrary constant used to utilise JavaScript in order to generate some random content for that pesky right column. This was done for two reasons: 1) to give the site a bit more depth and 2) to help me learn the basics of JavaScript. Now that both of these goals have been achieved, here is a guide detailing how it is done, which will hopefully prove useful to anyone new to this sort of thing.

Overview
Generating a random entity on a page can be split into three sections:

1) defining the entities you wish to choose between (i.e. text, images, banners etc)
2) defining a randomising function
3) using that function to return your desired entity

Each of these sections are dealt with in turn.
