This man was an absolute giant of design. (Along with his wife, who is also an amazing designer).

For those of you unfamiliar with his work. He created a lot iconic imagery -- including the signage and maps for the subway system in New York City.

A quick google search or visit to [0] will reveal his talent. Btw, I always thought this website was quite poorly designed considering the Vignelli's abilities.
