It's easier to understand the appeal of streamlined architecture when you consider the Romanesque style: not a inch of the building sits still. It writhes in all directions. Everyone thinks the late 19th century was such a solid, sober time - well, look at the details crawling over this mountain, and it's clear they had a wilder sense of decoration than we do today. It’s Sullivanesque in one spot, Egyptian in another. (The capitols in the columns at the bottom of the picture above, or example.)
It’s full of mysteries the layman may not grasp – note how the two spheres above the name are different. One is studded with stars and wears a band; the other is webbed, and looks like the World’s Fair Unisphere.
