Underwater scripts

Hi i was wondering if any one had a script to make it look like the screen was under water (first person) thx

There is a post about that here: http://answers.unity3d.com/questions/11283/is-there-a-tutorial-for-creating-the-underwater-effect-from-scratch

Check this thread http://forum.unity3d.com/threads/16540-Wanted-Ocean-shader?highlight=ocean+shader

Where is a unitypackage and it contains also underwater effects and bouyancy. If your objects have rigidbodies increase damping, reduce gravity and add small random forces to create the illusion of tides, currents, waves.
