The ball rolls from side to side (combine two transform functions) and it becomes grayscale and blurry (combine two filter effects).
The ball "pulsates" quietly to alert you to click on it.

The ball falls down, bouncing slightly over and over until it calms down.
The ball moves in a fixed pattern, just like in # 4, but every time it hits an edge it gets a little mast. You will need a lot of extra keyframes with transform changes!
