Below is a complete, self‑contained HTML file that creates an interactive 3‑D WebGL scene of the seastead design you described.
It uses Three.js (via CDN) and includes:
* **Three NACA‑foil floats** arranged in an 80 ft equilateral triangle, each 19 ft tall, 10 ft chord, 4 ft thickness (half submerged).
* **A triangular “big‑triangle” frame** at the top of the floats.
* **A space‑frame truss** made of many small triangles that connects the top of each float to a rectangular living‑area deck (14 ft × 50 ft) positioned 5 ft above the float tops.
* **A simple water plane** and basic lighting.
* **Orbit‑controls** so you can rotate, zoom and pan the view.
Save the code as an `.html` file (e.g., `seastead.html`) and open it in any modern browser.

Seastead Design – 3‑D WebGL Scene
Seastead Design
Tri‑float NACA‑foil arrangement (80 ft apart).
Each float: 19 ft tall, 10 ft chord, 4 ft thickness.
Space‑frame truss connects float tops to a 14 ft × 50 ft deck 5 ft above.
Drag to orbit, scroll to zoom.
