A geometric sans built from rounded-rectangle forms and straight horizontal terminals, drawn as an outline with a consistent inner inline channel. Curves are squared-off with generous corner radii, producing a soft, modular silhouette, while diagonals (V, W, X, Y, K) stay crisp and mechanical. The design maintains uniform stroke behavior and spacing logic across caps, lowercase, and numerals, with a notably large x-height and open counters that keep the letterforms airy despite the double-line construction.
Best suited to display contexts where the inline detailing can read clearly: logos, headlines, poster titles, product packaging, and interface or device-style labeling. It can also work for short blocks of text in larger sizes where the outlined construction and wide stance remain legible and intentional.
The overall tone reads as futuristic and tech-forward, with a distinct retro sci‑fi flavor reminiscent of neon tubing and instrument-panel labeling. Its clean geometry and repeated line motif feel precise and engineered, lending a sleek, high-tech atmosphere to headlines and branding.
The design appears intended to translate a modular, industrial geometry into a decorative outline system, using an internal inline to evoke illuminated tubing or technical striping. It prioritizes strong silhouette and stylistic cohesion for attention-grabbing display typography.
The inline channel creates a strong striped rhythm in horizontal-heavy letters (E, F, S, Z) and in the numerals, giving the font a sense of motion and circuitry. Rounded bowls (O, Q, 0, 8, 9) appear particularly stable and iconic, and the squared curves help maintain consistency at display sizes.
