Electronic Tatoo Display Runs On Blood

And another amazing link I just found in my inbox, this time from the deliciously geeky Harp Elf:

'Jim Mielke's wireless blood-fueled display is a true merging of technology and body art. At the recent Greener Gadgets Design Competition, the engineer demonstrated a subcutaneously implanted touch-screen that operates as a cell phone display, with the potential for 3G video calls that are visible just underneath the skin'

As you do. Wow.
