$100 Bill Redesigned, Now Has Hidden Images

Today the Treasury Department will reveal a redesigned $100 bill. The new design brings the bill in line with the smaller denominations that are already in circulation, and it adds a fancy new anti-counterfeiting measure called Motion that uses special threads to “create an optical illusion of images sliding in directions perpendicular to the light that catches them.”
