Turning function calls into animations.

Animated transitions are an integral part of modern interaction frameworks. With the increasing number of animation scenarios, they have grown in range of animatable features. Yet not all transitions can be smoothed: programming systems limit the flexibility of frameworks for animating new things, and force them to expose low-level details to programmers. We present an ongoing work to provide system-wide animation of objects, by introducing a delay operator. This operator turns setter function calls into animations. It offers a coherent way to express animations across frameworks, and facilitates the animation of new properties.
