Open the live demo Source on GitHubA 3D browser game that teaches the real mechanics of windsurfing. You control the same levers a real windsurfer has — sheet angle, mast rake, foot stance, body lean, daggerboard, harness — and the board responds the way a real one would. No rudder, no arcade shortcuts: you steer by trimming the sail, you plane when the physics say you can, and you get catapulted when you get greedy with the power.
