Unity Indie Screen Effects

My “horror” game lacks of a nice screen effect as for example the TV noise like in Slender or Fisheye like in Amnesia and I think the “scared sound” that the player will make won’t be enough, enough for the game to make you hmm tremble.

My Question is: What are the possible screen effects ( With scriptin or not ) that I could create for my horror game in Unity3 Free ?

You could put a transparent texture in front of the camera? And scale/move/otherwise animate it…

No post-process (screen space) effects in Unity free.

Well the trick is that you can’t do much via script - you need to write shaders (Pro only).

You might be able to do some cool stuff by scripting camera params - animating the FOV can look pretty freaky! You could get a “kind of” fisheye feel with that.
