A black screen with a mesmerizing pattern of swirling shapes and lines, reminiscent of a psychedelic dreamscape, with hints of purple and blue hues peeking through the darkness, and a subtle sense of movement and energy emanating from the design.

A black screen with a cracked and worn texture, as if it's an old computer monitor that's been left on for years, with a faint glow of static electricity emanating from the cracks, and a few scattered pixels of color still flickering in the darkness.

A black screen with a subtle gradient effect, giving the illusion of a dark, infinite space, with a faint glow of stars in the distance, set against a backdrop of a futuristic cityscape at night, with towering skyscrapers and neon lights illuminating the dark.
