$Seamlessly looping ASCII animation of a mysterious DNA double helix, slowly rotating and twisting in 3D. The strands resemble two interwoven X shapes, with sharp angular geometry and a dark occult cyberpunk aesthetic. Rendered entirely with terminal characters such as / \ | # * + . and @. Bright bone-white characters with subtle violet and amber accents against a pure black background. Retro underground hacker demoscene, experimental biotech, elegant and sinister. Fixed camera, centered symmetrical composition, smooth continuous rotation, readable silhouette at small size. No words, no logos, no background scenery.$
