As soon as I saw this assignment I knew I was going to do a tutorial about animation. I looked into animations a little when I was learning about CSS about 3.5 years ago, and I loved them.  Flash forward several years later and I hadn't even touched them since I first learned how they worked. I knew that you used @keyframes, but other than that all of the animation knowledge was gone. I took full advantage of this self study to make silly little shapes that change color, spin, and even one that my brain says looks like a frog jumping around.
