I’m only guessing that it has something to do with the fact that the moving circles are changing size, that it somehow makes the triangle do so as well.  
How would I go about keeping the triangle at a fixed size? (917, y, 950, y-15, 950, y+15)

```auto
flake[] flake = new flake[30];

float speed = 10;
int x, y;

void setup(){
 size(1000,800);
 for(int i = 0; i < flake.length; i++){
  flake[i] = new flake(); 
 }
}

void draw(){
  background(50);
  x = mouseX;
  y = mouseY;
  
  display();
  
  for(int i = 0; i < flake.length; i++){
   flake[i].show();
   flake[i].update();
  }

}

void display() {
 fill(0,255,0);
 triangle(917, y, 950, y-15, 950, y+15);
 
}

```

```auto
class flake{
  float y=random(height);
  float x=random(-width);
  
  float z = random(20, 100);
  float size=map(z, 1, 30, 3, 20);
  float speed=map(z, 1, 30, 0.1, 1);
  
  void show(){
    stroke(255);
    strokeWeight(size);
    point(x,y);
  }
  
  void update() {
    x+=speed;
    
    if(x>width) reset();
  }
  
  void reset(){
   y = random(height);
   x = random(-width,0);
   z = random(20,100);
   size=map(z,1,29,3,30);
   speed=map(z,1,29,0.1,1);
  }
  
}

```

In the `show()` method of the flake class you set the size of the flake using `strokeWeight()`. So it’s still using whatever the previous stroke weight was when you draw the triangle. Try including `noStroke()` before drawing the triangle and it should fix the problem.

As a side note it’s generally good practice to use capital letters at the beginning of your class name to make it clear what is a class and what is a variable. It also makes for more readable code. Like:

```auto
Flake[] flake = new Flakes[30];

```
