    Uber-badge-and-Feynman-book-2

    The DefCon Uber badge is given to winners of the various conference contests and bestows the winner with a lifetime of free admission to DefCon. This year's Uber badge, in the shape of a triangle, commemorates the anniversary of the Trinity test in the New Mexico desert in 1945, and Richard Feynman's role in the creation of the first atomic bomb. The badge is radioactive---a Uranium marble sits on one corner, a crystal skull embedded with a small vial of tritium sits on another, and the third contains a tiny remnant of radioactive material said to have been recovered from the Trinity test site.
