Editor's note: The discovery of the wheel allowed humans to supercharge their work lives, and the discovery of the ball did the same for our leisure lives. We all have that one ball that makes our hearts beat a little faster, whether it’s a soccer ball in our favorite team’s colors, a scuffed Rawlings baseball, or a fuzzy neon-yellow tennis ball. Find your favorite in this fun collection and bring some happy energy to your screens with a few Ball wallpapers!
