Water Enviroment tutorials?

Hello everybody.Does anyone knows how to make a water enviroment or do you know any good tutorial about this ?
Thank you in advanced

hmhm try it this way,
make a spotlight with a colormap* connected to its color node. assign a volume fog shader to the light.
You can then animate the U or V offset of the texture assigned as a color. or better use frame extention with multiple colormaps.

if you leave me your email address i can send you a scene i'v made.

Yes.Moor you absolutely right and i want to thank you and here too.
Also if this helps anyone i found a good tutorial about water enviroment .
