E-Paper Moves Closer
squaretorus sent in this story about electronic paper at the BBC. Seems that everytime any of the e-paper, e-ink, e-whatever companies have a new demo unit they run out and call a press conference. But none of it matters until they have ultra-thin, durable, flexible pages that can be manufactured cheaply...
I remember seeing an article in a technology magazine a few years ago about electronic books with electronic paper and electronic ink. Apparently, this ink, when charged, would flip from black to white (or something like that). So you could buy the electronic book, download a text from the net for a nominal fee, and have the book automatically typeset itself for the novel. They also touted its ability to do fancy things like animation, font size changes, etc. Never heard anything more about this though (not that I know of at least, but I may have missed something). Sounds like quite the concept, but the technology for some reason hasn't materialized into something mainstream yet.

No. E-paper, as far as I know, needn't any power to keep in order and can be done waterproof.
In its core, as I heard, it's just black and white-colored balls in oil between two transparent plastic sheets.
Xerox has had this going for a while. It's been demoed at retail stores (flexible hanging banners with changing messages).
Here's a list of on-line electronic paper resources gathered less than a year ago by Shawn Hellenius.
