Zane Rutledge has posted some of his early experiments with creating storyboards using Google SketchUp and an older version of Poser. This is exactly what I was talking about Zane, nice work!
Zane has nicely articulated the strengths and limitations of SketchUp as a ‘boarding tool. It rocks for creating architecture and blocking scenes, but it has no tools for creating and posing “actors,” and limited and confusing ideas about what a camera is. If Google could tackle these minor omissions, they’d have a tool that every filmmaker would embrace.
