Kieran Lafferty has written an open source UI control that displays a horizontal list of icons and accompanying text. The movement of the icons left and right is very smooth and there is an animated arrow that provides a nice visual effect.
The images and text are easily customized using a plist which is read when the control is initialized. You can also tweak the visual appearance such as cell size, gradient colors and the shadows.
