Eventually, I think, everything designed by a human - and perhaps anything "designed" at all, say, sand dunes - gets re-interpreted, re-built, re-worked, re-duced, re-whatever-ed. Business cards appear to be no exception. Check the new designs for identity cards at Ideo. More interesting to me is the design of their site navigation. Too bad they don't provide a way back to the home page from the Identity Card window...
