I've searched through the forums and even though several threads ask what would be the best way to implement a mirror, there doesn't seem to be an actual module that does it. Or, if so, those are extremely old threads (2003, 2004...).
It wouldn't be too hard to script it myself but I'm looking for something a bit flexible (distorsions, etc.) -- or at least I'd like to focus on scripting that bit instead of starting from scratch.
Do you know of any such mirror module, or a module that does something else but could be modified? (e.g. the Lake Reflection module or the Underwater module)
Something like this (http://www.youtube.com/watch?feature=player_detailpage&v=--WcU-az_6E#t=17s)? But no, it's not a module unfortunately.
