This is my first post, so ease up all you critics. My teacher wanted us to test the boundaries of animation with a ball - pretty much until it doesn't register in your mind and you think wtf... This is my attempt:

For some strange reason the non functioning test can't upload, so this is where added a couple frames to smooth the movement more.

What I learnt was that you can make a ball move from one side to the other in about 3fps though still hard to follow (in an animators terms which is really 6fps). My previous clip was 2fps from one side to the other, and without the in-between so the ball looked like it just appeared from nowhere.
