thats nice, how far away can you produce a screen that size (6', 8', etc...)

i was looking into a system and i was oging to try and mount it sideways in a closet and project it off a mirror thru the wall, or just mount it through a hole in the wall (the closet is litterally at a great height to place it, and i figure i just cut a hole in the sheetrock, mount the projector right up to it, place a picture over it and when it's party time just take the picture down and chill....
