I`m trying to make a short movie and one of the things i need is
reflections. I would use them for windows, water, glass and mirrors
so if any one knows how to make good animated reflections that would
be cool 
p.s if any one has nothing to do your welcome to help me [/u]
If you look through the list of tutorials posted at the top of the the Q&A forum, there are some in there (though they confused the hell out of me).
do a search for enviromental maps / mapping- thats what it is called in Blender-
Look here for an example of what can be done
https://blenderartists.org/viewtopic.php?t=4957
In the answers there is also the technique used.
