In the same Digg discussion I read of a novel glass replacement called Kwarx that is meant to be unbreakable and so could save all that sweeping up after your next drunken cocktail party and a purported announcement from Bill Gates that the next version of the Windows operating system, Vista, will be unhackable! Is this just a coincidence or is Gates hoping to exploit the sparkling character and shatter-proof nature of Kwarx to keep his Windows nice and clean?
