Architects Without Borders

"The 5-year-old group hosts Web-based competitions in which architects and designers submit plan proposals for sites around the world affected by war, disease or natural disaster -- an attempt to harness the Net's networking power to tackle humanitarian crises."

Says Cameron Sinclair: "Architects aren't normally in the business of responding to humanitarian crises. The online competitions are a way to put the resources and skills of designers around the world to work in a manner that's perfectly suited for them -- a way that can provide tangible and immediate benefit."
