Image rotating slideshow_

Image rotating slideshow.. ?

Or whatever # 6 on this site is..
http://www.efectorelativo.net/laboratory...
the site is in spanish and i don't know spanish grr. so if you've seen something similar could you send me a link ?? :) or tell me how you would search for this... its like on the tip of my tongue.. image rotating slideshow and similar phrases aren't cutting it.

I like mootools a whole lot but i don't care what its written in.. as long as it does what #6 does... where you just hover over (not click) the link to display the preview.



k thanks :}
