The dark, edgy sibling of Y2K futurism (late 1990s–mid 2000s): brushed metal and liquid chrome, wireframe meshes, deformed abstract 3D forms, lens flares, and dark iridescent blues and violets on near-black steel. Named after Andreas Lindholm's 2001 'Metalheart' design book and pioneered by studios like The Attik and Gmunk.
Primary actionA liquid-chrome or brushed-steel form fractured by wireframe mesh overlays, lit with a cold cyan-to-violet iridescent sheen against a near-black background, annotated with tiny technical mono type.
