I have a few samples of mass-produced pop-up books (designed by the studio I work for) in which LED lighting has been used, and I also recently finished making a handmade artist's book involving an arduino and interactive RGB LEDs. I'd like to talk about how simple lighting and electronics can add drama and interactivity in pop-up/movable books and other sculptural media.

If you haven't seen Jie Qi's "Electronic Popables" book project, I'd recommend taking a look!
