This is a fascinating engineering challenge! Let me create an interactive 3D visualization of this movable spar buoy seastead concept. I'll show the wing-shaped spar partially submerged, with all the key features you described.

This visualization shows your movable wing-spar seastead concept with:
**Structural Features:**
- Wing-shaped spar (10ft chord × 5ft thick × 39ft long) with airfoil-like profile
- 5 internal floor levels (battery/work/living spaces)
- Open platform deck (20×20ft) with safety railings
- Solar array (30×30ft) elevated above for shade
**Propulsion System:**
- 8 RIM-drive thrusters (4 per side) positioned along the submerged portion
- Animated glow effect showing thrust intensity
- Positioned for differential steering and pitch control
**Ballast System:**
- Cable extending 100ft below the spar
- Freely rotating fairings to reduce drag/vibration
- Ballast weight at the bottom
**Water & Motion:**
- Animated water surface with waves
- 70% submerged as specified
- Realistic heave, pitch, and roll motion
- Adjustable wave intensity and thruster power
**Interactive Controls:**
- Wave motion slider
- Thruster power slider
- View modes: Full view, Hide water, Cross-section
- Camera presets: Side, Top, Front views
- Orbit controls for free navigation
The color scheme uses marine-industrial tones with teal accents for active elements like thrusters. This should give you a solid foundation to visualize and present your seastead MVP concept!
