Crystal Geode Letters

Show [TEXT] in very heavy, blocky capitals made of rough gray-brown stone on a dark charcoal velvet backdrop under a soft spotlight. A thin glowing saw line sweeps down across the word, throwing short orange sparks where it cuts, and everything above the line becomes a polished geode cross-section: a dark rough rind at the edge, then concentric agate bands in blue-gray, white and lavender that follow the outline of every letter, and a hollow core. Violet amethyst crystal points then grow inward from the bands, faceted and glassy, deep purple at the center and pale lilac toward the rim. A slow light sweep makes the facets glint with tiny stars. Finally the stone closes over again; loop.
