This is a photo of a sunset in the little park around the corner from where we live (for a larger size, click through to the flickr page). I just shot 5 pictures by hand equalizing exposure and white balance setting. I later stitched them together in hugin and did a very minor amount of processing in lightroom. I kept it understated on purpose.
One of the nice things is that by using the rectilinear projection in hugin, you can effectively approximate an extreme wide angle lens. The widest I own is 18 mm on my 1.5 crop factor DSLR. This corresponds to about 27 mm on a 35 mm camera. Not that wide thusly. I would love to get myself something wider such as the wide tokina, but for static or relatively static objects, this approach works quite well and you'll get superhigh resolutions as a result. Much higher than you can get out of any current DSLR, even including the just announced full-frame canons and Nikons. This image, when stitched at the highest resolution, corresponds to about 32 Megapixels.
