Chicago-based political artist Michael Rakowitz has been working on a project called paraSITE since 1998 that tackles the issue of homelessness that is an unfortunate reality of all urban areas. His inventive approach seeks to reuse warm air that leaves buildings through outtake vents for portable and personal temporary homeless shelters. He has built and disbursed over 30 different designs through different urban sites in New York City, Boston, Cambridge and Baltimore. All shelters were constructed using temporary materials that were readily available on the streets. The image above was constructed out of clear trash bags, ZipLoc bags and clear waterproof packing tape on a budget of $5.00.
