very cool layout. this cardboard mock up reminds of this far out idea i had last month. I was wondering what artist would do in a post apocalyptic world, how and what would we use. So I made a cardboard robot (similar to our awesome cardboard weapons project) and my initial thoughts were that people would create and innovate toys from found materials (cardboard) for children to play and display. sorry for the off topic banter.
I think in a post apocalyptic world, landfills would become a main source of materials. To the point where they would be guarded as valuable property. Probably held by Mad Max-esque gangs.
