Art Brut — raw art — is the movement Jean Dubuffet founded in 1948 to champion work made outside the fine-art establishment: psychiatric patients, mediums, compulsive autodidacts. The visual language is dense, obsessive, and unapologetically crude — mud-brown grounds, oxblood marks, hand-lettered text crammed edge-to-edge with no breathing room. This design system channels that horror vacui energy into interfaces that feel handmade under duress, where every surface is filled and sophistication is the enemy.
