The Archigram Archives

Check out this cool site. The Archigram Archival project has collected the work from the architecture group "Archigram" and made the ideas, artwork, plans, and writings available online to the public through the following site. They have thousands of photos and illustrations about hundreds of projects that arose during the 50s 60s and 70s, largely went unbuilt, but still are recognized for their expansive influence on new thinking toward architecture. The projects range from expansive and near-impossible country-wide city plans (the 1,000,000 person city) to much more pedestrian efforts to create easier life, such as the drive-in home.

It's really cool stuff and simply such a large archive of work that there are DAYS of images to page through...awesome fine...check it out, here's the "projects" page...
