I found this wonderful chalkboard animation on one of my favorite blogs, The LuLu Bird (isn't that a cute name?!). I love the trail of smudged chalk and chalk dust left behind, from the previous drawings.
I did a little bit of animation in college and with my high school students, when I was teaching. Animation requires patience and dedication, two qualities which I greatly admire.
I hope you enjoy this video as much as I do.
