Metec developed a text and graphic display with an array of 120 by 60 pins.
The price was enormous, however. There is one at the University of Stuttgart
in Germany. I don't know whether any others were built.

There is also a recent text and graphic display driven by electro-rheological
fluid.
Search the Web for details of the ItactI project; http://www.itacti.com/ used
to provide details and links, but is currently a mess.
