Memento - story told backwards. Its a classic !
Irreversable is similar in that the scences are shown in reverse chronological order.
That's more the kind of thing I was thinking rather than just visual effect although i'm not saying visual effect can't be standout.
One of the examples I gave was POV effect
Rec is POV also.
I mean Avatar could be listed as it was the first major film in a new generation of 3D films.
