Triode is a geometric type system drawn in two versions, one composed solely from straight lines one from round dots. Each is drawn in seven weights all of which share common widths and spaces so that different styles can work together in multiple layers.

Like several other MuirMcNeil type designs, Triode explores the ways in which form and counterform can be constructed reciprocally, using a system of modular components at the baseline, x-height and cap height throughout to provide a rhythmically fragmentary pattern, contributing to the composition of word shapes that are highly ambiguous while they attempt to remain as readable as the tight constraints will allow.
