Filed under: Transportationtemporary vehicle paint" idea was a fine concept if you adored hassles, but Nissan's got a much cleaner approach for those who appreciate easy. Yep, the same folks who dreamed up that self-healing paint some two years back are now talking up their paramagnetic concoction, which purportedly enables motorists to change the color of their ride at the press of a button. The secret is a "special polymer containing paramagnetic iron oxide particles," which is applied to the whip's exterior; an "applied electric current then adjusts the spacing of small crystals within the iron oxide particles, and therefore affects their ability to reflect light and change color." Essentially, vehicles could rock a default color when turned off, and then your imagination could go wild once you turned over the ignition. If all goes well, expect to see commercial applications ready to roll by the time Fast and the Furious: 10 Times 2 Many hits theaters (or 2010, whichever comes first).
