special fx on iphone

Is there anyway to change the look of a scene similar to the motion graphics filters used in music videos? Like motion blur, black and white, and things done in afterFx. Can any of these be done on the iphone?

Full screen filters are a Unity Pro-only feature. You would need unity pro and the associated iPhone licenses for this.
