- `rotate(random(PI / 2, TAU));` rotates an object by a random angle between PI/2 and TAU (which is equal to 2*PI).

- `let colors1 = "5d565c-d7d7d7-c0dee4-edb136-e07958".split("-").map((a) => "#" + a);` splits the string of colors into an array using the "-" separator, and then maps each element of the array to a new array with "#" added before each color code. This is a concise way to create an array of color values.

- Yes, there are other ways to assign a set of colors in p5.js. One common way is to use the `color()` function to create a color object for each color value, like this:

```

let colors2 = [

color(93, 86, 92),

color(215, 215, 215),

color(192, 222, 228),

color(237, 177, 54),

color(224, 121, 88)

];

```

- `mySize = min(windowWidth, windowHeight);` sets the variable `mySize` to the smaller of the window width and height, which ensures that the canvas will fit within the window.

- `translate((width - mySize) / 2, (height - mySize) / 2);` centers the canvas within the window by translating it horizontally and vertically by half the difference between the window size and the canvas size.
