「IN FUN」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. IN FUN as geometric ice crystal letterforms set in two words perfectly centered at 78% frame width — "IN FUN" on a single line with wide spacing between the words. Near-black background with cold blue-violet atmospheric glow. Each letter surface shows mathematical ice crystal geometry — precise hexagonal crystal facets across letter faces, geometric crack patterns following crystalline structure lines, refractive light caustic patterns within crystal body. Cold internal glow from letter core. Fine geometric ice crystal particles in dark air. Ice crystal font: geometric brand identity, tech-cold aesthetic, precision design applications.
