Rails spinoffs - Aug 2005 - Scriptaculous - Sliders and resizing images

Hello,

I''m new to Ajax and Web 2.0 development and I noticed that one of the
things I want to hook up first are on the wish list for scriptaculous. 
Hopefully, I''ve sent my questions to the right place.  Has anyone done
any work so far on sliders with the prototype.js library?  Also, I would  like
to resize an image/div on the page.  I see we have some functions for resizing
elements but I''m unsure if someone has hooked that into a mousedown
(and drag) event.

Cheers,
Marty
