「ECHO」は FontVibe AI で作成した割れたガラスの文字エフェクトです。鋭いガラスの破片へと砕け散り、外へ向かって飛び散ります。衝撃の中心から放射状に広がるカミソリのように鋭い破片と、ギザギザに走る亀裂。映画のワンシーンのような、迫力ある破壊の質感です。

shattered broken glass letterforms — each letter exploded from a central impact point with radial spiderweb crack networks. Three-tier shard fragmentation: large primary shards near impact core nearly flat; medium secondary shards tilting 15-45° outward; small tertiary splinters detached and floating in mid-air. Every glass shard face shows distinct optical behavior: front-facing shards catch brilliant white specular highlights; tilted shards reveal blue-green glass tint at thick edges; suspended splinters fire needle-sharp white glints from all four edges; crack intersections scatter concentrated white light. Peak visual moment: a constellation of needle-thin edge-glints from every floating shard — glass frozen mid-flight at maximum kinetic energy. ECHO rendered as shattered broken-glass lettering against a deep charcoal-to-black gradient field with faint pitted concrete texture. Each character carries a distinct impact core, with radial spiderweb crack networks branching through translucent glass planes. Three-tier fragmentation creates frozen impact depth: large near-flat primary panels preserve the readable word silhouette; medium shards cant outward at 15–45 degrees, exposing saturated blue-green glass thickness along fractured edges; tiny detached splinters and slivers hover around the break lines. A harsh directional white spotlight cuts across the glass, driving extreme chiaroscuro: forward shard faces flare with sharp near-white reflections while receding planes disappear into dense black shadow. Every suspended fragment emits needle-thin white edge glints, forming a precise constellation around the word. Crack intersections concentrate pinpoints of white light, with fine glass dust motes suspended through the beam. Crisp ray-traced refraction, hard specular highlights, razor-clean shard edges, high-detail cinematic render, frozen at the maximum outward velocity of a glass impact.
