Me and my son looked at this tonight.
We have been taking baby steps and much of this code is way beyond our level as we follow the “Learning Processing” book and tutorials by Daniel Shiffman. We sertanly notice progress by the fact we are actually seeing things in the code examples more now than before!. 
Really cool! 
There is some things we couldn’t figure out.
Our bubble is made with variables all along so everything connects. This is so we can set it to a different size and the wobble will adapt.
When we tries to do this with the “bullets” (now renamed fallouts in the code) we cant figure out how to change this.
We changed the “final float RADIOUS = 1,8” to a variable called “rad” that is based on the bubble dimeter/2. This worked to make the fallout start from the bubble edge
Then we want to be able to change the number of fallouts depending on the size of the bubble but this we couldn’t find.
The number seems to be hardcoded here:
final float ANGLE_INCREMENT = TWO_PI/10;
and
for (int i=0; i<10; i++) {
I tried using fallout.lenght and “i” but it didn’t work in this case?
We also want to change how far and how fast the fallout moves. We want to have it move a bit less and maybe try some small random here. Could find where to do this?
Is it possible to create the dots a little more random around the circle? just some pixels? So it doesn’t look so perfect
Then we cant figure out this:
class Fallout {
// Bullet
float posX, posY; **// pos and dir variables crated, no values..**
float dirX;
float dirY;
int fade = 255;
Fallout (float x, float y, **// x,y,dx and dy variables created, where do they get there values from?**
float dx, float dy) {
posX = x; **// variables with values taken from somewhere and used where? Now getting what value**
posY = y;
dirX = dx;
dirY = dy;
Also some small question marks.
- Why is riseY reminding the program of its original values in FALL already and not in RESTART?
- The default state? when does this appear? And the exit() line. Does it close the viewer?
Played around with it some more and this is what I came up with…
Still cant figure out a lot of the above…

void setup() {
size(640, 360);
b1 = new Bubble(50);
}
void draw() {
background(0);
b1.all();
