「FROST」は FontVibe AI で作成した凍った氷の文字エフェクトです。分厚い氷の塊に閉じ込められた文字。鋭くカットされた氷のファセット、内部まで深く走る霜のひび割れ、そして垂れ下がるつらら。実写のようにリアルな氷結の質感です。

rendered in deep-frozen solid ice letterforms — each letter a massive glacial ice block. Surface: smooth-polished outer ice face with faint frost micro-crystal bloom at letter edges and surface rim frost texture. Body: thick translucent ice with pale blue-white tint, internal air bubble inclusions caught as bright white spherical highlights, faint crack networks branching inward from surface stress points. Internal: deep cold glow emanating from letter center — subsurface scattering of cold light through the ice mass, brighter at core, fading toward edges. Optical behavior: incoming light refracts at the polished ice surface creating bright rim caustic lines at letter edges; internal ice density variation bends light into cold blue-white spectral micro-prisms; icicle extensions at letter bases show pure refraction clarity — crisp cold caustic light fans below. Peak visual moment: cold internal glow + surface frost bloom + refracted rim light + hanging icicle drips = letters physically frozen in time. Reference: blue glacier ice cave walls / Arctic sea ice block at dawn / Jökulsárlón glacial lagoon ice / professional ice sculptor competition piece under cold spotlight. Square 1:1 composition. Render the exact text “FROST” as the sole monumental centerpiece, occupying 78% of the frame width against a near-black arctic midnight expanse. The letters are physically deep-frozen solid ice, luminous pale blue-white glacial bodies with smooth polished faces, thick translucent depth, and a fine bloom of frost micro-crystals clinging to every outer edge and rim. A deep cold glow radiates from within each ice mass, brightest through the central cores and fading into denser blue edges. Internal air bubbles appear as tiny suspended white spheres; delicate branching crack networks spread inward from subtle stress points. Bright refracted caustic lines trace the letter contours and spill as crisp icy light fans onto the dark frozen ground below. Long clear icicle drips hang naturally from the letter bases, catching the internal glow. Behind the word, a broad blue-teal aurora borealis unfurls softly across the upper background, giving the ice luminosity a cold atmospheric halo without introducing any warm color. Fine airborne ice crystals and sparse drifting snow glint in the aurora light. The lower frame holds a barely visible mirror-smooth frozen surface with fractured reflections of the glowing word. Zero warm tones: only black-blue shadow, teal aurora, and spectral blue-white ice light.
