Create a content slider using Tumblr or RSS as input

I have a website and a tumblr blog(s) and I am looking to integrate the two to create some dynamic content on the website that is easy to update via the tumblr blog(s). What I would like to have is a horizontal slider like [login to view URL] or the slider in the middle of this page www.nikeinc.com. The slider would automatically update the content preferably from a Tumblr account, RSS feed or yahoo pipes account (depending on which is easiest to create a seamless look and feel on the website).
