@mousso: it is not really a water prop at all.  It is a set of shader nodes designed to simulate different bodies of water connected to a flat plane.  To achieve maximal affect, you should use it in association with BB's Envsphere or Terradome.  The link is below:

I own a collection of various props from space ships to small everyday items.  Like SamTherapy, you never know when you need it.  Currently, I have been playing with Terradome and very recently acquired some DMI vehicles to test shaders.**
