Стимпанк Диорама Неудачных Изобретений

A prompt for generating an image of a detailed diorama set on a wooden desk, illustrating a timeline of four failed inventions from different historical periods (300 BC, 1400 AD, 1700 AD, 1900 AD). The scene uses a steampunk aesthetic, cluttered with blueprints and gears, under warm workshop lighting.
