Titanium non-electronic puzzle badge
A Ryan Clarke / 1o57 DEF CON 19 badge that intentionally stepped away from electronics and used a waterjet-cut commercially pure titanium physical artifact as the event credential, puzzle surface, role marker, and social-interaction prompt.
Non-electronic PCB playing-card puzzle badge
A Ryan Clarke-designed DEF CON 21 badge series built as poker-card printed circuit boards: non-powered identity artifacts whose copper, soldermask, silkscreen, inner-layer metal, role variants, and encoded face-card relationships formed a cryptographic and physical badge challenge.
Playable vinyl-record noir puzzle badge
A Ryan Clarke / 1o57-designed DEF CON 23 badge issued as an actual playable 7-inch vinyl record, with role-colored editions, printed mystery alphabets, inner-groove markings, lanyard ciphers, record audio, and a noir-themed badge challenge.
