For this animation, it took 19 drawings. There were actually 20 but i forgot to put the last one -.- ... That' why the end goes buy sooo quick.
Ps: good equipement for animation is photoshop, a camera, and a light table. (or just a glass that you can put a lightbulb under it). With some animation paper that you can by at OmerDessert and the little plastic thing to hold theme together you should be ready to try.
