This is my image.

When you move the mouse around, the square on the right bottom will show a bigger version of the section where your mouse is.

When mouse is pressed, it’s going to show this:

the circles have white strokes around them, so it looks like it’s snowing.

If you keep clicking, the stroke weight becomes heavier which makes the snow look heavier.
