🌊 Ocean Tides from Moon and Sun: Equilibrium Bulge, Spring and Neap Cycle and a Live Tide Gauge

Earth, Moon and Sun in 3D with the equilibrium tide computed from the tidal potential: the two ocean bulges, the 12 h 25 min lunar tide, the 14.8-day spring-neap beat, orbit eccentricity and axial tilt, plus a tide gauge you can place at any latitude.
