Lion-like scrollbar with jQuery?

Interesting stuff, I wrote a plugin that does just that. It's called LionBars.

Antiscroll is probably one of the best plugins available that recreates Mac OS X Lion scrollbars in every browser.

Some of the great features of Antiscroll:

1. Fades in and out
2. Size of container can be dynamically adjusted and scrollbars will adapt
3. Supports mousewheels, trackpads, other input devices natively
4. Shows scrollbars upon hovering
5. Supports IE7+, Firefox 3+, Chrome, Safari, Opera

nanoScroller.js is a jQuery plugin that coded with Coffeescript and it makes its job: http://jamesflorentino.github.com/nanoScrollerJS/
