Designed by Robert Schenk, HeptagroanMono is a novelty font family. This typeface has two styles and was published by Ingrimayne Type.
If there is ever a need for a heptagonal font, that is, a font based on a seven-sided polygon, Heptagroan may fit the bill, unless the need is also for true lower-case letters. Heptagroan is caps only, though some of the caps on the lower-case keys differ from those on the upper-case keys. Heptagroan is monospaced and is available in two weights.
