“Happy Birthday Rivah” es un efecto de texto Vidrio creado con FontVibe IA. Mayúsculas de vidrio óptico transparente que refractan la luz, con brillos intensos en los bordes y cáusticas, reflejadas en una superficie oscura bajo una aurora verdeazulada.

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. A polished birthday greeting with the exact words “Happy Birthday Rivah,” arranged in three centered lines: “Happy” above “Birthday,” with “Rivah” largest and leading below. Keep every word crisp, fully visible, and easy to read, with generous clear space around the lettering. The letters stand upright on a smooth reflective surface, their transparent glass bodies bending and enlarging the pale lavender-blue gradient seen through them. Bright caustic light spreads in delicate fan-shaped patterns beneath the words, with sharp white highlights tracing the changing glass edges and subtle inner reflections revealing the material’s depth. Surround the greeting with a few small, carefully spaced clear-glass balloons and slender curling glass ribbons, kept secondary and transparent so the background remains visible through them. Add tiny points of cool white light reflected across the surface, but no confetti or opaque decorations. Soft, even studio illumination keeps the scene airy and celebratory, with a gentle blue-lavender glow behind the lettering and a clean uncluttered finish.
