Hasn't everyone longed to personalize a room by drawing on the walls? Down on Paper is an interactive wallpaper sample book with three categories of design possibilities.  There are dot-to-dot designs familiar from children's activity books; note-taking designs that turn walls into surfaces for personal writings; and coloring-in designs, with outlines of flowers, picture frames and the like.  All the designs can be printed to order, to fill walls of different dimensions.
