This creates an interactive 3D WebGL scene of your seastead wing-spar design. Here's what's included:
**Structural Elements:**
- **Wing-spar body** — NACA-style symmetric airfoil, 39ft tall × 10ft chord × 5ft thick, with the bottom 70% submerged (orange waterline ring marks the waterline)
- **8 RIM-drive thrusters** — 4 per side along the thick part of the wing in the underwater section, shown as dark cylindrical pods with red hubs
- **5 interior floors** — visible when you enable "Cutaway View" (checkbox), color-coded with batteries/heavy floor at the bottom
- **20×20ft platform** with railing on top of the spar
- **30×30ft solar canopy** above the platform on support poles, with a grid of dark solar panels
- **100ft ballast cable** dropping from the spar bottom with 8 freely rotating fairings and a cylindrical ballast weight at the bottom
**Interactive Controls:**
- **Click + drag** to orbit the camera around the structure
- **Scroll wheel** to zoom in/out
- **Cutaway View** checkbox to see the internal floors
- **Show Water** toggle
- **Wave Height** and **Time Speed** sliders
**Visual Features:**
- Animated ocean waves with proper lighting and fresnel reflections
- Underwater fog effect (submerged parts get a blue-green tint)
- Specular highlights on the water surface
- Different coloring for above/below waterline portions of the hull
