Programmable Tattoos

Bonkers report on the posibilities of a subdermal display. Basically, you get a thin membrane implanted under your skin, which on certain areas of the body (hands, face) is translucent. The membrane is controlled by an implanted chip, which can receive WiFi and hence can programatically change the image displayed.

Imagine using it to monitor your vital signs, or to have a permament post-it note on the back of your hand. It could aslo be useful for those with impaired function to get messages across, such as mood, by displaying emoticons or text messges.

I think it would be interesting if it could display a translation of what you were saying to help in foreighn countries.
