This is a neat short animation showing five notable skyscrapers in Chicago. (Although we Chicagoans still think of the Willis Tower as the Sears Tower, we will let it go this time.) We especially like how the Marina Towers, also known as the Corn Cob Buildings – mmmmm mmmmm, just ready to be buttered up like a good fresh cob – seem to grow row by row, from the bottom up. Thanks to the excellent graphic skills of this artist, Seba Rodriguez.
