A hyper-saturated 3D scene in which the walls and floor of a plain white room peel back to reveal a surreal, rainbow-hued mountain landscape. Billowing, cartoonish mounds undulate underfoot like glowing clouds, while the ceiling morphs into a psychedelic aurora of swirling colors. The lone figure stands in awe at the threshold, cap casting a faint shadow as prismatic light washes over him. The vibrant peaks and valleys appear to breathe and ripple, alive with electrifying neon shades that defy reality. Everything warps and twists in a vivid hallucination, merging the mundane with a fever-dream fantasy.
