What is Spring-Based Animation?

No matter if you create animations for the web, Android or iOS - spring animations are becoming more and more popular. In traditional, time-based animations an animation is defined by a start point A, and end point B, a duration and some easing. If you design a single, static animation, this is a very intuitive way to work. However, when it comes to designing continuous, fluid interactivity, this approach is very limited.
