Note NIH maybe :)
Although I normally avoid carousels I'm sometimes required to include them. There are a couple of excellent options (see below), but most of those opt for features over filesize. This is fine, of course. It's just that I often don't need 50% of the features and would rather have a very simple, modular script. Including a carousel plugin that requires dozens of KB's simply to make something 'slideable' seems wasteful.
Strangely enough I've not found many robust carousels that are simple, modular and lightweight... (Currently http://unslider.com/ (see below) seems to come pretty close)
