Mr. Lohmueller has one at: 
http://www.f-lohmueller.de/pov_tut/backgrnd/p_wat3.htm
and there's another at the short code contest #5: 
http://local.wasp.uwa.edu.au/~pbourke/exhibition/scc5/final.html
Both are using surface normal's, not actual deformed surfaces (Alex 
Kluchikov's is amazing nonetheless).

Not finding something like this for isosurfaces but probably out there 
someplace (perhaps use Alex's function anyway?). Somebody else might know.
