One of the very important things I learned this week was how to transform all the hard-code elements I did to variables. The other thing was before doing drawings in p5 editor, use illustrator or sketch to visualize it. I feel like p5 is not very flexible when you want to change something afterward. So it would be better to have the thing you want to make in mind before start making it.
Here is the link to this week's sketch.
This week I had some fun with 'random' and transparency. These functions make the code much more dynamic and interactive, instead of being a static picture.
