Is this what you mean? If so, then its very easy to create...I didnt even need to use the lattice editor. Just find an image of an old book and apply it to a stretched cube...set its bump level to the desired amount, and viola! If you wanted to put borders/decorations and or your own text on the book (or calculator), its easy enough to do in PS. Just create a white or light gray decoration or text against black background, then make a lattice out of it. Also you can make a neat effect of indenting the decoration/text by booleaning (is that even a word?) with your book cover (just make cover positive and text/decorations negative).
