Oh, and by the way... I didn't win with my shot-in-the-dark guess of Mexican architect Juan O'Gorman. But at least I didn't think it was Wright, Barragán, Neutra or Siza like many others apparently did. I wouldn't say that any of those architects qualify as "lesser-known" with the exception of Wright... but what do I know.
