Anyone with shelves cluttered with Christmas cards might hope that an
idea from Robert Barreca and Karen Hurley of New York catches on. Their
British patent application 2 264 897 shows a Christmas card formed from
cutouts, and covered with coloured transparent filters. The card comes with
adhesive strips, so that you can stick it to a window. Light shines through
to create a stained glass effect.
