The word PRISM rendered as massive brutalist typography composed of cascading refracted light beams and swirling rainbow spectrum ribbons, each letter formed by crystal glass formations and floating light particle dust in electric violet and luminous emerald green, oversized bold text emerging from infinite transparent crystal cavern depths, Swiss grid composition shattered by light refraction distortions, deep obsidian and pure crystal white palette with blinding white singularity highlights and pure diamond edge accents, volumetric light particles and floating spectral wisps, experimental typography poster art meeting optical physics aesthetics, hyper-detailed 3D infinite crystal cathedral environment with stained glass windows, dramatic center-out perspective through towering letter prism monoliths and spiraling light beam arches, ethereal magical transcendent mood
