Spanish Researcher Invents Electric Chameleon Fingernails
Spanish scientist Carlos Gonzales has invented fake fingernail technology that changes color at the flip of a switch. A device is placed over the special glue-on fingernails, which is used to set the color. It has a digital camera, so colors can be captured, then "transferred" to the nails. The fake nails are made from layers of electrochromic polymers, which change color in response to electrical currents from the gadget.
