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

but re-wrote it in CG
