CNNgo.com

CNNgo.com is a sister site to CNN.com. The "Hero" is a custom slideshow module with many bells and whistles:
Ads can be inserted into the Hero at any of the 6 available slots - Doing so removes the last Hero in the sequence keeping the number of Heros in the widget at exactly 6.
A rollover pauses the slideshow, darkens the Hero's Opacity, and displays the title and teaser text describing the linked article.
A click on one of the six nav buttons will take you directly to the sequenced image.
