Oops, did we put this in the wrong section of the gallery? No, this is a 2-D effect, made with a single call to 2-D noise on a 2-D plane. The only object in the scene is a single quad that covers the viewport, rendered with an orthographic projection. There's no perspective view and no three-dimensional rendering going on here -- it's all faked by the fragment shader. The "refraction" in the "water" is a simple coordinate displacement along the noise gradient, scaled well enough to be visually plausible, but far from correct.
