Fun animation noodles

I had some fun noodling with animation. I’ve never done  or learned animation before but had an idea how it works. I’m not familiar with any animation tools or softwares etc., so I first tried painting that Raygun breakdance girls movements on corners of book pages (see first video below ). I was fascinated by the result. I got kind of hooked and did another one but this time I painted sketches of a ballerina movements on separate sheets, then took pics of them (18 sketches !) then placed them sequentially in my iPhone movie editor then sped it up (see second video below) . It was a lot of fun and I think everyone should try it especially if you draw or paint.
