Metalheart vs Vectorheart
メタルハート / ベクターハート
Metalheart comes from UI Expression and Vectorheart from Digital Retro. They are reached for with some of the same intent, which is where they get confused.
Metalheart

Early 3D software gave this fin-de-millénaire style its chrome, liquid metal, aggressive bevels and lens flare. Dressed in techno and science-fiction imagery, it ruled rave flyers and games magazines around Y2K.
Vectorheart

A graphic style compressing Y2K speed into sharp vector forms, industrial symbols, and high-contrast type. Flatter than Metalheart's heavy 3D chrome, it turns Swiss modern and machine-display order into aggressive bevelled angles.
| Metalheart | Vectorheart | |
|---|---|---|
| Era | 1995–2004 | late 1990s–mid-2000s |
| Family | UI Expression | Digital Retro |
| Kind | Style | Style |
| Cues | Liquid-metal chrome / Aggressive bevels / Lens flares / Techno and sci-fi typography | 45-degree notches, arrows, wings, and speed lines / Extreme contrast between very heavy and very light type / Numbers, warning rules, coordinates, and fictional industrial labels / Monochrome or dark fields with one red, yellow, or cyan accent |
| Best used for | Club and rave announcements rebuilt with the texture of that era's 3D · Showing off technology through excess instead of refinement | Game, sports, and electronic-music identities built from technical symbols instead of 3D · Reconstructing Y2K graphics through vectors and typography rather than chrome |
| Type | Extrude the letters, bevel them deep, and bake in mirror reflections | Attach tiny monospaced labels and numbers tightly to an angular ultra-bold headline. |
| Composition | One large object at center, the ground filled with grids and beams | Run one 45-degree direction through headline, arrows, and image crops. |
| Material | Chrome, liquid metal, lens flare, reflections carrying surrounding color | Use flat vectors, thin warning lines, and limited color, creating depth from overlap and cuts rather than bevels. |
| Caution | Polishing it clean in current software removes the rawness that came from the crude renderers of the time, and it becomes something else. | Chrome and bevel effects turn it into Metalheart. Vectorheart gets speed from flat cuts, disciplined symbols, and a unified angle. |
