FH Blue by Dan Meyer is a free futuristic monoline display font with slender, rounded strokes. Its open joins and squared curves resemble paths traced across a technical diagram.
Circuit-like lettering can become part of interface graphics rather than simply labeling them. It suits technology branding, electronic music artwork, game menus, and science-fiction posters, echoing screens and schematic lines. Its clearest audience is designers working with digital culture and understated retro-futurism.
