Gyrotrope is a wide, rounded, geometric sans-serif inspired by typefaces of the 1960s such as Microgramma and Eurostile, as well as contemporary takes on the genre such as Vernon Adams' Michroma.
Like Gyrochrome — a direct derivative of Michroma that was my first attempt at a typeface in this genre — Gyrotrope exists because I needed a 1960s-futurist typeface for a project, in a rounded style and a range of weights, on a DIY budget.
