Cardboard shelters for the homeless aren't exactly the newest concepts on the block (that's what refrigerator boxes are for, right?), but NYU grad student Carolina Pino's thesis project, the collapsible Shell House [1] (with embedded radio transmitter), is a practical DIY project that provides a simple and bare-bones, yet attractive and effective barrier against the elements and others. She's even posted instructions [2] online so that the authorship dissolves in order for the project to evolve via users.
