Just as an interesting aside, the same thing could happen with film cameras that have focal plane shutters. The shutter moves a slit across (and in some cameras, vertically) the film.
There's a famous photo of an old race car taken by a French photographer (I can't remember his name), and the car, especially the wheels, appear to be slanted forward. The shutter was a upward-traveling one, so the early part of the exposure was at the bottom of the frame, as as the latter part of the exposure was made, the car had moved forward.
@thedarkhorse: Except for the GH1 which has somewhat crummy codec implementation and a lack of live output (at least after hitting record) but also has the least rolling shutter jello of any vDSLR and even less than most CMOS camcorders, even on shots with lots of fast, lateral movement.
It's really not at all there or noticeable with that camera. In fact the only time I've ever really seen it was when doing motion-stabilization in post production, wherein the motion of the shots is removed, and we're left looking at a static shot...then, (and even then only sometimes), do you see rolling shutter with the GH1.

Yep, that's the one! I wish I could remember who shot it.
