Live examples

These are all from the article linked above, and are in the tree in examples/

• Android Wear back gesture—physics animations vs CSS transitions
• Springy Button—simple spring usage
• Various Falling Dialogs—using the Fall simulation, which combines Gravity with a Spring for a soft landing
• Windows 8 Lock Screen—using GravityWithBounce, which is a hard landing
• Vertical Scrolling—combining Friction with a Spring to make springy scrolling, now with a more iOS-like overscroll equation
• iTunes Radio continuous scrolling—constant velocity combined with Friction to create an interactive continuous scrolling list
• Floating Action Button—uses multiple Springs and some state to create a Floating Action Button that works in one continuous gesture
