<p>[Free + Open-source] Block icons are inspired by Bauhaus design principles. The free version offers geometric, minimalist icon designs. Licensed under the Creative Commons - CC BY 4.0</p>

**Summary**: Fully opaque Bauhaus-style solids on a 16px grid — the hardest, densest set in the catalog. Sharp rectangles and perfect circles as the only construction primitives reflect the Bauhaus principle that form follows function literally. The tone signals machine-aesthetic institutional precision: this is the only Vault set with full dark-mode native performance, and the only Vault set suited to small-size compact UI contexts. Best for high-density developer tooling, data engineering interfaces, and admin panels with a Bauhaus or Swiss modernist visual identity; carries a free CC BY 4.0 license.

### Emotional Scores

Vault Block is one of the colder sub-styles in the catalog — full opaque black fills with Bauhaus geometric construction carry no warmth cues, though circle usage moderates the effect slightly. It is among the hardest sub-styles in the catalog — fully opaque fills with sharp rectangle corners represent one of the hardest visual weights in the catalog. It is somewhat formal — the Bauhaus institutional register reads as structured and serious. It is one of the more serious sub-styles in the catalog — zero decorative elements with pure functional geometry throughout. On its human↔mechanical character, it is one of the more mechanical sub-styles in the catalog — Bauhaus construction is the definitive machine-aesthetic in design history.
