I've been playing with printable transparency film to make customized windows.

If you do print them, be sure to print at 100% (do not shrink to fit in A4 or other paper size. Also, be sure to use transparency film that is printable in your printer. If you use the wrong film, you will end up with either smearing or a destroyed printer (if the laser printer heating drum melts the film).
To use them, cut the image out closely to the edge. They will pop into the [url=https://www.bricklink.com/v2/catalog/catalog ... ge?P=60593]1x2x3 flat front window[/url]. You can then cover the film with the glass insert (wedging the transparency between the frame and the glass).
