From Stephen's Lighthouse... Tattoo Touch Screens"Imagine! A touchscreen on your arm as a subcutaneous digital display powered by your own blood. It could be a video phone, a calculator, or more.
Just think - spam, phishing, and begging phone calls delivered directly to your body. Here's one idea I hope never comes to fruition. (Of course the technology that drives this could have excellent medical uses that do make a difference.) I don't even want to speculate about what the upgrade path looks like. Imagine aging gracefully but having the tattoo equivalent of a rotary dial phone permanently inked on your arm."
I'm with him. This is one scary, albeit obsessive, invention.
