TreeHugger has a great article on the RSID kids kicking some reuse butt as only art students can.
This year is different; the theme this year is RAW. Media director Naomi Tallin explained in an interview:
Raw is raw process, using raw materials, raw salvaged materials, the fundamentals that we learn to get us to a final refined project. We are trying to balance how the show has really refined finished pieces and show the visitors the in-between, the process. How do you represent that in a material way? We felt that the only way we could do that was using, reusing, and salvaging, and minimizing waste.
