There's a lot to hate about the internet (constant distraction, lack of privacy, too much information about whichever distant relative just got on Facebook), but one thing I always love is that it's a kind of living time capsule. I just happened to scroll all the way down my YouTube channel and rediscovered an animation I made for a class a few years ago!
It's not especially advanced, but it was a great exercise and I'm pretty happy with the final product. (Especially since it loops nicely.) Always pleasant to be reminded of old projects you're still proud of!
