I am not looking forward to my prelims, I've heard some stories... =/ Also, I forgot to comment on your earlier post about your lesson plan today. It always cracks me up when students sound shocked that something (like an activity or an example) turns out to be pointedly relevant, as if we planned it out in advance!

As for your challenge: Arthur/Eames, Washington DC, The International Spy Museum (http://www.spymuseum.org/) :D
