1. This paper describes a method to augument direct manipulation HCI with
techniques from cartoon animation.

2. This paper aims to improving the visual feedback of direct 
manipulations
by smoothing the interface change, giving manipulated objects a feeling of
substance and providing cues for anticipation.
3. The approach is to add support for animation techniques and to provide
prepackaged animation effects.
4. Key contributions:
	1. it describes a set of animation effects based on those used by cartoon
animators that extend the visual feedback for direct manipulation
interfaces;
	2. it shows the effects to be effective and enjoyable for users;
	3. it shows that convincing animation effects can be effectively
incorporated into a significant application, a drawing editor.
5. Improvments and Extensions
1)  Be careful to avoid distracting users from the key activities by
animation
