**Here is a complete, self-contained HTML file** that creates an interactive 3D WebGL visualization of your seastead using Three.js.
```html
Seastead - Tensegrity Platform
Seastead • Drag to rotate • Scroll to zoom
```
**How to use:**
1. Copy everything above into a file called `seastead.html`
2. Open the file in any modern browser (Chrome/Firefox/Edge)
3. Drag to rotate, scroll to zoom, right-click drag to pan
The model includes:
- Correct 50 ft equilateral triangle at ~8 ft above water
- 24 ft legs at 45° with proper tensegrity cables
- Underwater triangle for redundancy
- 25 ft tall triangular pyramid living area
- 4 banana propellers (2 on each side leg) pushing toward the back
- Realistic water plane
Would you like me to add stairs, windows, or a night/sunset lighting version next?
