Rebound

Build Status Android Arsenal

About

Rebound is a java library that models spring dynamics. Rebound spring models can be used to create animations that feel natural by introducing real world physics to your application.

Rebound is not a general purpose physics library; however, spring dynamics can be used to drive a wide variety of animations. The simplicity of Rebound makes it easy to integrate and use as a building block for creating more complex components like pagers, toggles, and scrollers.

For examples and usage instructions head over to:

If you are looking to build springy animations for the web, check out the Javascript version.
