In terms of concept, I created an 600,600 frame animation which has bubbles of random sizes with each bubbles having different widths and heights and that if you drag the mouse along the frame it will form more and more bubbles a bit like what you would see in chemistry reaction. I also added a gimic where it shows hello in 7 different languages. For let x = random width and let x = random height I ended up with function ask different bubbles, at different widths and heights at random place. I commented on specific hard parts of the code such as the bubble class and interaction functions, this makes the logic very easy to follow.
In terms of the code I am particularly proud of the code from the Bubble class section which is lines 42-50 and 53-60. As I set variables X, Y and R where bubbles form at X, Y, R but they are random and that anything within frame of setup will do only once. (Generate 30 bubbles then no more), but anything after background 220 would do and run in the output again. I also set it to move random within the scope (-2,2) so that it could create reaction between bubbles not too fast and not too slow about right. And I chose to fill the bubbles with random colours and also not having stroke for the bubbles to be more beautifully designed. I then realized that I wanted to do (-5,5) but that would mean that the bubble would be reacting to each other too rapidly, so I had to go watch some of the Object-Oriented Programming examples from Dan Shiffman’s coding tutorials from the links below:

I think what I could improve for the future would be separating different features such as bubbles, greetings, UI text into their own files and clearly labeled section so the sketch stays clean as there is more code. I also think adding more interaction logic, such as limiting how many bubbles can appear, letting users delete objects, or adding animations to the greeting text instead of just putting it there.
