<https://s.mj.run/BYi8KFGlAcM> A dark room with a square hole in the middle, the walls made of a pixelated texture. The walls are covered by a large number of colorful pixels, which reflect light and create an abstract pattern. There's a gradient from purple to green at the top, giving it a futuristic feel. In front, there's a large empty space for text or product display. This is a high-definition photograph that captures every detail of these elements, creating a unique visual experience.
