Henri Genaille's Rods are a nineteenth-century device for doing multiplication,
similar to, but easier to use than, the more familiar Napier's Bones. Genaille's
Rods are visually attractive and useful in teaching. This article shows
how to use Mathematica to draw the required diagrams, which can
then be cut out with scissors and passed to wooden rods to make an accurate
set of rods.
