“…The AJAX SharePoint List 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…”, Adam Buenz
