Top bar for WP sites with carousel

Hey,
On my WP multisite, i want to have a topbar on the sites, that shows some selected sites on the network.
You can see a site here that has the feature i'm looking for: http://www.lavishlavish.dk - i have also attached an image.

I have tried some different topper plugins, but can't find any that let me have a carousel effect, so that the users can click left/right to show more sites.

Help please!
