Sometimes, you want to rotate items out of a SharePoint list on a random basis in order to make this information available to your users, for example, some items that might be housed within your enterprise portal that would be helpful to rotate on something like your intranet frontpage displayed in no specified order are:

So, without further a due, a shocker of a WebPart, the AJAX Rotator WebPart.
The AJAX Rotator WebPart does what its name implies; it rotates things out of a SharePoint list. In order to eliminate a postback, it uses AJAX to load and rotate the items, nothing really fancy, but I needed a way to display task items randomly in a WebPart. To be honest I didn’t spend a lot of time on it because it was a nice to have thing, and not really used that heavily for my side project (I had under an hour to deliver it), so I just kinda whipped the damn thing out. It does take into account like object disposal etc., but I am sure some things could be cleaned up and other things introduced that would make it a little bit more applicable for other persons use. I dunno, I might be interested in doing something else with it, but hey, it was written on a whim really quick so I didn’t have the luxury of being that clever.
The AJAX Rotator WebPart is packaged within a SharePoint solution file (AjaxRotator.wsp) and the deploy.CMD file that will deploy your solution to your server. Once the solution if deployed, it is very, very easy to configure.
After successfully SharePoint Solution deployment On Your SharePoint Server:
Activate the SharePoint feature for the AJAX Rotator WebPart by going to the site collection features of the SharePoint instance by going to:
Site Actions -> Site Settings -> Site Collection Features -> activate the AJAX Rotator WebPart Feature
Once the feature is activated, add the WebPart to a WebPart page by going to Site Actions -> Edit Page
Once the WebPart is added, it must be configured by setting the WebPart properties, these are grouped under two sections, List Configuration and Labels and Message.
The first section is just the configuration options that are required, like the web where the list lives and the name of the list that should have its items rotated. There are some other configuration options that you can implement as well like if you want to pull a secondary field for display, and if there is a lot of characters that would normally be pulled from the secondary field, you can truncate that amount, if desired (you have to enable the truncation by selecting the checkbox). In this section you will also choose the rate of display that you would like items to be rotated in and out (I use 3000, but hey that’s just me).
The Labels and Messages section lets your adjust some of the textual interface components like the text that is used for the read more section, what text you want when items are loaded, etc. etc. etc They are pretty self explanatory.
I have only tested it with a task list, I haven’t tested it with any other types of lists. I am assuming because the code is kinda ambiguous it should work, but don’t get mad when it doesn’t. Like all the software that I release on this site, read the sharepointsecurity.com software disclaimer before you download it.

Anyhoo, you can download it here.
