When I began freelancing at Ogilvy I was asked to prepare some storyboard images and sample animations for one of a series of supermarket ads featuring 3D kinetic typography in simple environments. The theme of this ad is the frantic hurly burly "to-do list" lifestyle of the average suburbanite. I was allowed a crack at some creative, and Cinema 4D really came into its own.
In all I came up with about a dozen images, and used Cinema 4D to put together "3D sketches." One of the advantages of this of course is that it's not necessary to create separate scenes to storyboard things such as camera moves or lighting changes. You just build the scene and move around it, taking "snapshots" as you go. I found that it was much faster, and a much more accurate way of communicating the look of a shot than drawing is.
