Project Three - Coding Exhibition

At this stage I have chosen the term 'variable'.  I understand this one well because I have used it a lot in both of the previous projects.
On the Learning Processing web help site, I found this very simple definition:

Variables.

'Variables are used for storing values.'

I think that this is the first and obvious thing that comes to mind when talking about variables, but variables are also useful for saving time, they can change a code a lot - by only changing a number.

A good example of the use of variables is actually from my wallpaper

This link shows the first wallpaper in the series, everything is in order and symmetrical.

The link above shows how by adding variables, the end result changes completely.

A really simple example of a variable changing the way code works is this one :
