Just move your mouse around!
This is my first Parallax! It took me a while to figure out how the coding works, but when I did I really liked the results. (The hardest part was doing almost all of the stars by hand. Two hours of clicking non-stop...) I added the sparkle effect later. I figured it needed something to make it distinctive, and that was it. I also intend to add shooting stars later. :) Hope you like it!
