Hi evanlitw. I'm not sure what you want this effect to produce.
To my eye, you are reflecting the view vector (per-pixel) and using that direction to sample into a cubemap (which looks to have the same texture on each of the 6 faces).

If you want ripples, etc, then you'll need to figure that out mathematically. Not an easy thing to do, that's for sure.
If you have copied the shader from somewhere else, then I guess some value isn't being correctly passed in - or it might be assuming some render/texture state is set.

Unfortunately, I don't know how I can help. I'm not too sure what it is you want, or the context of the problem.
- Sorry
