A weathered, dust-covered optical computer mouse lying abandoned on a dark wooden desk, its red sensor light flickering weakly like a dying heartbeat. The mouse cord trails off limply, frayed at the edges. Dramatic chiaroscuro lighting casts long shadows, giving the scene a melancholic, end-of-era atmosphere. Tiny cobwebs connect the mouse buttons, and microscopic dust particles float in a single beam of warm afternoon light. The perspective is low and intimate, as if paying final respects to a fallen companion. Photorealistic style with shallow depth of field, emphasizing the texture of years of use worn into the mouse's surface—the faded logo area, the smooth-polished thumb rest, the grimy scroll wheel. Mood: quiet dignity of obsolescence.
