Probably the most common display used by the older transport sector which occupies both bus roofs and rural train stations. Also known as a Flip-disc display, they consist of a grid of small metal discs that are black on one side and yellow on the other. A microcontoller is used to flip the dots and inturn form characters and symbols. It is often compared to the similar 'core memory' process where both x and y axis wires are charged with a current, creating a magenetic field where they cross, which interacts with a small magnet on the discs edge. The desired discs are then flipped by using just a enough force to flip each one. This will take a couple of seconds to do the whole screen but it is said that the sound of the flip which occurs is 'quite distinctive.'
This type of display may be of use to me, as due to the analogue flipping nature of the screen refresh, it still makes a natural sound. This I think will still create higher 'associative bandwidth' than a simple LCD monitor. Hopefully this LED looking electro-mechanical medium will have the desired effect on the audience by portraying the high bandwidth procedure of navigating the Internet through a linear action low data bandwidth medium. It is this restriction to the instant visual access of the Internet that I am interested in controlling making the user aware of.
