Quantum Flat Hollow (BRK)

Quantum Flat Hollow, by ÆNIGMA Fonts, is a free outlined modern display font with a clean retro-futurist pulse. The letters are built from smooth, tubular strokes with squared turns and open interiors, giving the alphabet a sleek electronic feel that lands somewhere between early sci-fi signage and late 20th-century tech branding.

It works well anywhere you want a graphic title rather than a text voice: music sleeves, arcade-inspired posters, tech event graphics, packaging, and title cards all suit this free font. Because the forms stay broad and airy even as they interlock and curve, it also makes strong short headlines, logos, and monograms where that hollow neon-line look can do the talking.
