Bonacci is a typeface that utilizes aspects of Bidoni and the fixed ratio of the Fibonacci Sequence. Although Bonacci preserves the extreme thick and thin strokes of Bidoni, it aims to find a balance between the elegant characteristics of Bidoni (serif) and the geometric characteristics of Futura (sans-serif).

The Fibonacci Sequence, aka the Golden Ratio, bridges the conflicts between the opposing characteristics of Bodoni and Futura.
