I ended up grabbing an anamorphic lens filter (the Cinemorph) from Vid-Atlantic to see what fun could be had with it. The filter can be found here: http://www.vid-atlantic.com/cinemorphic.html.
I shot with my Nikon D7000 and a AF-S Nikkor 28-300mm 3.5-5.6 G with the 77mm Cinemorph filter.
A nice soft rainy day on our office rooftop in Kansas City. The footage has been cropped, some of the wind shake was warp stabilized, and no grading was done except in-camera temperature modification.
I'll likely check out what I can do with some night shots in another test down the road.
