Eternity Version 2.0

For this updated version, I have reorganised the functions() and tried to keep the draw() as clean as possible. I have also added mousePressed(), so when mouse is pressed, a random colour will be filled in the rectangles.

To start from the logic from beginning, I have in total created 5 functions():

1. drawRect() : for drawing the first set of rectangles repetitively

2. drawRect2() : for drawing the second set of rectangles repetitively

3. moveRect(): to make the rectangles move

4. mousePressed(): to fill the colour of the rectangles when mouse is pressed

5. writing(): to write the text "ETERNITY" at the end

One main feature I used for this project is the recursion concept I saw from The Coding Tain challenge #77 by Daniel Shiffman when I were exploring calling functions. Basically, a recursive function is a function defined according to itself. It's a really convenient way to create patterns compare to using a for loop, so every time it draws a rectangle, it calls itself, which could result in an infinite loop. Thus in this case, my exit condition is when x position of the rectangle is smaller than 1, it stops drawing. And by multiplying 0.9 to the positions and the length of the width of the rectangle, I got the shrinking size working!

There are a lot of other things I learnt during the process, for example, the push() and pop() allows you to constrain certain arguments in a function. I have used it for drawing the second sets of rectangles, to constrain that the translate and rotate only applies to the rectangles but not anything else.
