Here is an animation made through FlippaClip. If you like drawing then there’s no reason not to like this animation app. It’s simple to use and doesn’t take too long to create a decent little animation - or it could take a long time if you have the patience. It’s old school animation in a modern app. Draw something then continue to repeat what you’ve drawn with a slight change each time to give the illusion of movement. Just like the little flip books that used to be quite common.
I like the beginning of this animation, it seems fluid and natural. I guess a seemless flow of ideas is what attracts me. The flow does not continue until the end in my opinion but it’s good to try out different ways of creating motion.
