Reimplementation of JellyFish shader

[VpSnipes]

The jellyfish shader has been absent from Garry's Mod for quite some time now, I'm not sure as to the specifics of it; though I've had to go to great lengths in order to get similar effects via refract and sub-surface scattering as shown here:

Problem is that this still doesn't get the desired result despite the constant material editing and param changing. Could we get this shader re-added to Garry's Mod with the adjustments it needs to get working?
