Ajax Fade - in Popup

Hi there,

i am in search for a script like this one: http://www.mediahof.de/cms/open-source/joomla/modules/joomla-ajax-popup-modul

But not as joomla module. I just want to the stripped popup-stuff to implement in an other kinded website.

If anyone knows something like this, its really appreciated much!

The main thing is i can control the position of the appearing.

Thank you!
