This is a fascinating engineering project! Let me create a detailed 3D visualization of your seastead design with all the key elements - the angled buoyancy legs, cable system, banana propellers, and solar array.

This visualization includes all the key elements of your seastead design:
**Structural Elements:**
- **Living Area**: 40x16x8 ft structure with windows on the long sides
- **Four Buoyancy Legs**: 4 ft diameter, 24 ft long cylinders at 45° angles from the corners, with dished end caps and water-line markers
- **Cable System**: Diagonal cables from leg bottoms to platform corners, plus the rectangular cable connecting all leg bottoms
**Propulsion System:**
- **4 Banana Propellers**: 2.5m diameter curved-blade thrusters mounted on the underwater portion of each leg, extending 5 ft behind
**Solar Array:**
- **Top panels**: Covering the living area roof
- **Fold-down panels**: Deployed on both sides and the back, 8 ft wide as specified
**Interactive Features:**
- **Auto Rotate**: Slowly rotates the entire platform for viewing
- **Wave Motion**: Gentle bobbing and rolling motion simulating ocean conditions
- **Thrusters**: Animated spinning propellers
- **Day/Night Mode**: Toggle between night sky with stars and day sky with brighter water
**Visual Details:**
- Procedural ocean waves with realistic shading
- Underwater caustic lighting effects
- Stars with twinkling animation (night mode)
- Fresnel water reflections
- Water line clearly visible on legs (half underwater as specified)
