ไดโอรามาสตีมพังก์ของสิ่งประดิษฐ์ที่ล้มเหลว

A detailed diorama arranged across a long wooden workbench, showcasing a chronological timeline of failed inventions from four historical eras: [300 BC]: a miniature failed invention model with a small parchment tag explaining briefly why it failed; [1400 AD]: a miniature failed invention model with an explanatory label; [1700 AD]: a miniature failed invention model with a short explanatory tag; [1900 AD]: a miniature failed invention model with a short explanatory tag. Steampunk aesthetic, tabletop cluttered with rolled scrolls, technical blueprints, brass gears, and inventor tools under warm, ambient workshop lighting.
