I got curious, tried something out, and it worked. I was wondering if panning with a moving object and forcing the use of the electronic shutter on the XT would give me a slanted background but a vertical subject, and it did indeed. If there's anyone not familiar with "rolling shutter," I'll try to define it quickly:
When a camera uses the electronic shutter, what it's doing is reading out the pixels from the top left to the bottom right, scanning line by line like an old cathode ray tube TV. So if you've got fast motion (subject OR camera), the image will "lean" one direction and slant, because by the time the sensor gets to scanning the bottom pixels on the sensor, things ain't exactly where they used to be. Instead of motion blur, like you'd get on a physical shutter, you get a crisp tilt.
So in this case, I was panning with the cyclist, and shot at 1/5000 (I think). Note the buildings leaning left, but the cyclist looking normal. He was still in the same spot during my 1/5000th of a second, start to finish, but the bottom of the buildings had moved over a few feet.
