waves/ripples patterned density map applied to scattering media? .... almost 
completely transparent. between the camera and object to distort the view. I 
also just recalled that you may be able to apply a distortion to the camera, 
not 100% sure! The former idea seems like it would be a localized effect, 
while the later would have a gloabal effect. Hope that gets some ideas 
flowing .....
