From ABCnews.com comes this – it is one of those cool ideas which makes one wonder why no one thought of it before:
Sub Media, cofounded by Spodek and Matthew Gross in 1999, produces 15- to 20-second animated ads that appear on subway tunnel walls. This is accomplished through a series of backlit pictures which Spodek compares to “the frames in a film reel.”
The pictures, printed by the U.K.’s Photobition Group on Kodak transparencies, spring to life as the train speeds by, creating a fluid film and giving passengers the effect of being inside a giant flip book.
I haven’t yet seen it, but from what I’ve been told, there is also one in the Hong Kong subway.
