With jQuery Runloop, you can create your own small runloop with keyframes at your own choosing, each with code to execute. You can put whatever code you want in each keyframe, rearrange keyframes easily, and use reusable maps of code and/or animations to share between runloops.
Runloop was created to have more power, more control and less hassle than dealing with jQuery .animate() callbacks. It hooks into jQuery's Effects Queue by design, to avoid timing conflicts in the case of doing many multiple .animate() calls.
Currently there are no known issues for the 1.0.3 release.
jQuery (1.5 and below) has a bug in its .animate() step: method, which triggers an error in IE8 and below. The 1.0 version, however, has sidestepped this by using "top" instead of "z-index".
