This is my first time using processing, thus to get in touch with it, I’ve took an example and started changing some parameters to see what happens.
First of all I’ve changed the background and the coordinates of the rectangles.
It is possible to see how much the drawing alters just with those simple changes.
After that I started playing with other things as the location of the rectangles in the canvas or the stroke.
Till now I’ve only changed what already exists but I haven’t tried to write anything.
