Niobium Black by Levente Halmos is a free geometric display font with a dense, blocky silhouette and smooth round openings that keep it from feeling blunt. That mix of broad vertical mass and simple circular shapes gives the lettering a compact sign-like presence instead of a purely industrial one.
Posters, music flyers, game titles, packaging, and bold web headers all make sense here, especially when short words need to read as solid graphic forms. The rounded interiors stop the design from turning harsh, which helps it anchor logos and cover art without losing the sturdy punch that defines it.
