A lavish, futuristic auditorium with dark marble walls, a circular stage, and a large glowing wireframe brain hologram floating above it.

Lavish, windowless private auditorium with a blend of ultramodern architecture and surreal design elements. The walls are made of deep black marble with subtle golden veins, segmented vertically by narrow amber light strips embedded into the stone. The high ceiling arches above in a geometric lattice pattern, matte black with recessed warm lighting. The stage is wide and slightly curved at the front, its floor made from polished black obsidian so reflective it mirrors anyone standing on it. Around the perimeter of the stage floor, a thin illuminated trim glows in soft silver. Floating directly above center stage is a massive holographic sculpture of a human brain, built from shimmering silver filaments and translucent geometric patterns, slowly rotating. The audience seating is arranged in a semi-circle with tiered rows of plush, dark charcoal upholstered chairs, each row separated by a slim illuminated aisle. Integrated into the walls and ceiling are concealed holographic projectors that send shifting geometric shapes into the air above the audience. The atmosphere is cinematic and moody: warm amber light softly bathes the audience while cool silver-blue light spills from the hologram onto the stage, with faint haze in the air to catch the beams.
