jQuery Flying Popup, by Damian Szewczyk (netkevin)
damian.szewczyk@gmail.com
Version 1.0
Flying Popup plugin for jQuery. Allows to show floating HTML popups that follow page scroll/resize (also static HTML popups can be shown when desired). Popups can fly in from outside of the screen (from every direction)
See example usage in readme.txt or run index.html for useful creator
