Kyouei Design's flashy bookmark
The tech-savvy may prefer to read e-books from tablets these days, especially since one of the advantages is that the device is often backlit making it easier to see text in dim environments. Printed matter, however, never seems to lose its charm, and there are still plenty of people who prefer to carry a paperback around with them. Keeping a reading lamp at hand, however, is not so convenient.
Kyouei Design's Bookmark Light is a great idea for bibliophiles. It's thin enough to be an unobtrusive marker when not in use and when bent in half, it becomes an effective reading light.
