Speaking of ice, as icicles are governed by gravity, they will drip vertically. They don't have precise linear shapes, so it's tricky, but they can serve as a guide.

We really should eliminate the use of the term "level" as the term "plumb" conveys the issue much more precisely - too many horizontal lines that aren't level to the frame when an image is plumb.
