Visualization of 4 Lesser-Known Inventions

I asked Nano Banana to visualize 4 lesser known inventions. Can you tell what they are? Prompt: a 2x2 grid, do this prompt for 4 lesser known historical inventions: A museum-quality diorama presented as a cross-sectional view, photographed straight-on, showing both exterior and interior of [INVENTION] simultaneously. PRESENTATION FORMAT: - Wooden shadow box frame, 24" x 18" implied scale - Deep set (6-8" depth) allowing layered construction - Glass front panel with minimal reflections - Museum placard at bottom: "[INVENTION NAME] - Cross-Section Model" EXTERIOR HALF (left side): - Pristine exterior view of [INVENTION] in period-appropriate finish - Original paint colors, manufacturer decals, period branding - Wear patterns appropriate to era and use - 1:6 or 1:8 scale model - Environmental context: floor/ground/mounting surface INTERIOR HALF (right side - cutaway): - Exposed internal mechanisms with color-coded components: RED: Power/energy components BLUE: Control mechanisms YELLOW: Safety features GRAY: Structural elements - Visible gears, springs, wiring, pistons as appropriate - Small numbered tags (1-12) identifying key components - Miniature cross-section showing material layers INVENTOR ELEMENT: - 1:12 scale figurine of [SCIENTIST] positioned at bottom - Standing with pointer or gesturing toward mechanism - Period-appropriate lecture attire - Small podium or presentation setup - Audience silhouettes in deep background (optional) TECHNICAL ANNOTATION LAYER: - Thin clear acrylic overlay with white etched lines - Arrows pointing to specific components - Minimal technical callouts in sans-serif font - Flow arrows showing movement/energy path - Exploded view diagram in corner BACKGROUND ELEMENTS: - Schematic blueprint visible in deep background - Patent drawing fragments - Historical photo of actual device in use (sepia-toned) - Timeline showing evolution of technology LIGHTING DESIGN: - Front lighting illuminating exterior - Internal LED strips highlighting cutaway mechanisms - Dramatic shadows between layers - Colored accent lights matching component coding - Spotlight on inventor figurine BASE DISPLAY: - Component samples laid out: gears, springs, wires, materials - Original patent document under glass - Manufacturing specifications sheet - Trade catalog page showing device MATERIAL DETAILS: - Polished wood frame with brass corners - Museum-grade felt lining - Precision-machined miniature components - Authentic materials (brass, steel, copper, Bakelite, etc.) - Weathering and patina appropriate to era PERSPECTIVE: Completely straight-on orthographic view emphasizing technical illustration quality COMPOSITION: Perfect bilateral symmetry - intact left, cutaway right ASPECT RATIO: 3:4 (vertical) or 4:3 (horizontal) depending on device orientation STYLE: Technical museum exhibit, Smithsonian Institution cutaway displays, How Things Work illustration aesthetic
