It's only a matter of time before stuff like this is commercially available. I don't see the point in LEDs, though.

Code:

The light-up implant, the Northstar V1, is about the size of a two euro coin, making it considerably smaller than its predecessor, the Circadia 1.0 computer chip that Grindhouse Wetware cofounder Tim Cannon had implanted two years ago. "This is about passion and citizen science." Österlund makes an incision with a small scalpel and lifts Sarver’s skin to make room for the implant, which is about as thick as a thumb. Sarver winces as blood flows from the opening while Österlund pushes the implant into his arm. Then Österlund stitches up the wound and tapes over the implant. It’s all over in 15 minutes.
