Well, here's an absolutely ridiculous fashion trend. Japan's Takara Tomy Arts has created a collection of stick-on fake fingernails featuring embedded LEDs and tiny antennas that light up whenever the wireless NFC functionality of a nearby smartphone is being used.


Each set actually only comes with one LED-enhanced nail; the rest just feature matching designs. And surprisingly, there are no batteries, capacitors, or other connected power sources required. The energy from an NFC signal is all that's needed to make the LEDs flash.


From what we can tell there's an accompanying Android app as well that will let users customize when the fingernails flash. And a set should cost somewhere in the neighborhood of $12—cheaper than a manicure and far more flashy. [Takara Tomy Arts via Akihabara News]
