The Pocket Plasma is a 3" screen you can wear anywhere you'd like to get kicked in the nuts. It's supposedly bright, and probably has nice contrast since it's covered in glass. The "lightning" responds to environmental sounds, like all the people who will say, "Nice Pocket Plasma!" and mean it. It also works with music.
It runs off two AAAs and will set you back $45 if you don't mind the international order or the pink slip from the man club.
