It depends on how you want them to rotate. Here is an example http://groups.google.com/group/grasshopper3d/web/boxRot.jpg
In this image the box param is fed into a rotate component. The rotation angle is driven by a range component in order to generate different rotation angles for each box. In this case the last boxes will rotate more than the first boxes. Just an example, sure there are many ways to do it.
