To get an aesthetic PNG wallpaper, you can use the anime-wallpaper package. Here's a brief snippet to get you started:

npm install anime-wallpaper

Then, you can use the following code to fetch and display a random anime wallpaper:

const animeWallpaper = require('anime-wallpaper');

animeWallpaper()
  .then(wallpaper => {
    console.log(wallpaper);
  })
  .catch(error => {
    console.error(error);
  });

This will output the URL of a random anime wallpaper. You can then use this URL as your desktop wallpaper.

Note: Make sure to install the package and run the code in a Node.js environment.
