Update: the contest is over, we have two winners with two great ideas!

Last week we posted about E Ink display persistency - and the fact that those displays can actually retain an image for years. Now it's your turn to try and think of applications for this feature.

Just post your idea as a comment below, and be sure to leave your e-mail (you can also send the e-mail address in private, of course). We'll choose the two best ideas, and award them with new e-readers (either a Kindle paperwhite or a Nook Simple Touch with Glowlight). This content is open for everyone. E Ink, who were kind enough to give away the two e-readers, will ship them worldwide. We'll choose the new winners on December 11th.
