「Happy Crystal Anniversary」は FontVibe AI で作成したガラスの文字エフェクトです。光を屈折させる透明な光学ガラスの大文字。明るい縁のハイライトとコースティクスが、緑青のオーロラの空の下、暗い面に映り込みます。

sculpted from high-clarity optical glass — letters cast from pure transparent glass with intense light refraction through the material body. Brilliant caustic light patterns projected below each letter. Sharp specular highlights trace the letter edges where glass thickness transitions. Slight organic surface tension gives letterforms a subtle liquid-pulled quality at terminals and curves. Deep internal optical depth visible through the glass. Purely transparent — no frosting, no color tinting, no opacity. LETTERFORM PRIORITY: when the chosen font carries its own treatment, that font's letterform shapes take priority and own the letters; this style governs the optical-glass material, the refraction and the caustics. FALLBACK MATERIAL: if the font carries no material of its own, render the letters as high-clarity transparent optical glass with intense refraction, sharp edge specular highlights and bright caustic patterns cast below. COLOR PRIORITY: keep the font's own colors if specified; otherwise pure clear glass with no tint. Render the exact text “Happy Crystal Anniversary” as the hero typography, sculpted from high-clarity transparent optical glass with substantial dimensional depth and clean polished surfaces. The letters contain deep internal refraction, sharp white specular lines along every thickness transition, and subtle liquid-pulled tension at curved terminals. Preserve pure colorless glass: the lavender-blue environment remains visible through the letter bodies, optically bent into soft distorted bands. A pale lavender-to-ice-blue studio gradient surrounds the text, with a smooth reflective surface catching bright caustic pools, prismatic arcs, and fine rippled light projections beneath the glass. Add tiny suspended crystal facets and sparse clear glass beads in the surrounding space, each producing pinpoint reflections without competing with the words. Use broad diffused overhead illumination combined with a crisp rear edge light, ray-traced transparency, realistic dispersion, internal reflections, and high-resolution optical caustics. Keep generous uncluttered negative space, a refined celebratory scale, and pristine product-photography clarity. No opaque fill, no metallic coating, no dark background, no colored tinting, no additional words.
