When in D.C., I always make an attempt to visit the National Building Museum. I got the chance to do so today (wrapping up our workshop here), and the NBM has done it again with their fantastic Liquid Stone exhibit, all about concrete, its history, its engineering, contemporary uses, and where its headed.
That was a great exposition – I think the Building Museum could have used the Web site to show other works which were as relevant but didn’t make it to the show.
And because I’m the nagging Brazilian, I suggest you check out the work of Oscar Niemeyer. There aren’t that many great Web sites about his architectural work but there are some awesome books out there. Meanwhile, here’s a list photograph sources: http://tinyurl.com/4d7jd
