For anyone who has ever been freaked out by the idea of getting a tattoo, here’s a new invention that will really make you squirm: the Digital Tattoo, an implant which sits beneath a layer of your skin and shows up as a tattoo-like electronic interface. Here’s where things get really weird—this gadget can work as a phone or computer. So, yes, you could literally press a button on your skin and answer a call. Or, explains Geekologie, it can just look like a “traditional tattoo by downloading a picture of a unicorn from the internet.” Whaaaa??? What’s more is that it is powered by your very own blood. That can’t be good for you.
