    I did something similar for the local school my kids go to, these are 9 and 10 year olds. I took some sheets of cardboard, tape and a pocket full of flat steel washers. Once the window was closed off with the cardboard and a 4x4" hole cut in the centre it was a simple matter of changing the washers (on another piece of board) until we got something that worked. The process took maybe 5 minutes and we used about a 20mm hole projected onto a wall about 3 metres away.

    The image was bright enough to see after standing in the room for about a minute, this was on a dull overcast day. The most interesting thing about it was the super wide view. It covered the side walls as well as the one opposite the hole.
