I never tried, but I don't think this would work. AIUI, it has a minimum
and a maximum spacing for the lines.

The white noise sheet "works" because some the black-white-black
transitions come with the right spacing, no matter what that spacing is (it
has to be the right order of magnitude, and it doesn't work as well as the
real thing). Crumpled tin-foil has been reported to work, too.
