Windy is a jQuery plugin that allows a rapid navigation through a pile of items using some CSS 3D transforms and transitions. The effect of a continuous navigation flow reminds of a deck of cards or sheets flying away, hence the name.
There are several options available, including defining the range of spreading the items when navigating, speed (CSS transitions), adding custom navigations, etc.
For browsers that don’t support CSS 3D transforms or transitions, there will be a simple fallback, i.e. normal navigation of the items (appear/disappear).
