Seastead

Foil-legged semi-submersible habitat with minimal drag and a soft trimaran-like ride. Three NACA-foil legs provide buoyancy and stability.

``` This creates a complete interactive 3D visualization of the seastead design with all the described components: **Structure & Geometry:** - Three NACA 0030 foil-shaped legs (10ft chord × 3ft thickness × 19ft tall), half-submerged at the waterline, positioned at each vertex of the triangle frame - A triangular truss frame (80/80/40ft sides, 7ft tall) with main chord members, vertical posts, and X-bracing - Transparent glass panels filling the truss bays on all three sides - A dark floor and solar-panel roof covering the triangle **Details per the description:** - **Ladders** on the leading edge (front) of each leg, above the waterline only - **6 RIM drive thrusters** (torus ducts with blade geometry) — one on each side of each leg, 3ft up from the bottom - **3 stabilizers** shaped like small airplanes at the trailing edge of each leg — each has a 10ft-span wing with a 25%-chord notch at center, a 6ft fuselage, and a 2ft-span elevator that gently animates - **14ft RIB dinghy** (with orange inflatable tubes) oriented sideways at the back center, hanging from two support arms with catenary ropes - **Back deck** — 5ft-deck extensions on both sides of the dinghy with safety railings - **Solar panels** across the entire roof with a grid texture **Atmosphere & Animation:** - Animated ocean waves with semi-transparent water revealing the submerged leg portions - Gentle seastead bobbing motion - Stabilizer elevator oscillation simulating active trim control - Drifting sea-spray particles - Gradient sky dome with depth fog - Warm interior point lights glowing through the glass - Full orbit/zoom/pan controls
