Shader Week, Day 7

Last day on my shader week. Not sure what to do when a friend of mine suggested that I do a “wobbly water shader”. Well, I guess you could do it pretty simple by using a displacement map as in day 2, so I used another approach manipulating the vertexes with a sine-wave instead.

I used this tutorial as base http://www.alcove-games.com/opengl-es-2-tutorials/vertex-shader-for-tiled-water/ but re-wrote it in CG
