The Gothamist has an item about the TWA terminal at JFK’s which apparently was designed by Eero Saarinen. The terminal has been closed for a couple years: it reminds me of a map for Half-Life, or better yet, for any third generation Quake-driven game. See for yourself (picture courtesy of Lightningfield).
Saarinen, a Finnish-born American was clearly obsessed with curves. His Gateway Arch (St. Louis) is still one of the most discussed objects. Whether you like it or not, it has clearly redefined St. Louis’s skyline.
