Artist Evan Roth has devised a clever way to communicate with TSA workers as you travel home this holiday season. He explains:

T.S.A. Communication is a project that alters the airport security experience and allows the government to learn more about you then just what’s in your backpack. Thin 8.5 x 11 inch laser-cut sheets of stainless steel comfortably fit in your carry on bag, simultaneously obscuring the contents you don’t want the TSA to see while highlighting ideas you do want them to see. Change your role as air traveler from passive to active.
