"Nicktoons Network is giving away flip books that play back full-motion clips from two new original animated shows Skyland and Kappa Mikey. The books will be distributed
through Nicktoon Networks' first cross-country mobile tour, at Comic-Con International and during the Nicktoons Network Animation Festival at Nicktoons Studios.
Originally invented in 1882, flip books create the optical illusion of motion when images stacked in sequential stages of movement are flipped. Recognized as one of the earliest forms of interactive multimedia on record, flip books are now coming back into style as an innovative new marketing tool."
