Floating fractal island with mostly...

Floating fractal island with mostly flat glowing surface. Central infinite staircase structure (spiraling quartz) that loops visually. Repeating geometric pillars (glass/concrete) in rainbow order scattered around. Kaleidoscope mirror platforms (white glass) reflecting colored beams. Swirling pattern floors using dyed terracotta in spirals. Small floating crystal shards overhead. Flat open areas between structures. Detailed with all concrete colors, stained glass, sea lanterns, and shimmering particle effects. No fixed spawns. Void below with ever-shifting rainbow sky.
