I am trying to find the plugin called Carousel, but it doesn't seem to exist anymore. Where did it go.
Carousel was renamed to Flow
Just download Flow, the two plugins are identical.
There is a blog post about the change here: http://blog.yourhead.com/carousel-is-now-flow/
The new Flow homepage is here: http://yourhead.com/flow
And the download links are:
