I can’t imagine why you’d ever want to do this, other than to show that it is possible. A random modder who calls himself Datamancer has managed to stuff a full-sized flatbed scanner into a leather bound book. On the outside, it looks like an ancient tome filled with infinite wisdom. On the inside, you’ll find some modern imaging technology that is essentially useless without tethering itself to a computer.
Yup, a hardcore James Bond gadget this most certainly is not. That is, unless you manage to shove a laptop into a similarly shaped ancient leather bound book. Then you can carry around two tomes and scan to your heart’s delight.
