Capture the Flag Qualifying
CYBERFOXES
I · The Rite

A sculpture, fracturing into signal
CYBERFOXES is a jeopardy-style Capture the Flag competition. Solve challenges, capture flags, and climb the marble. Every problem is a chisel-strike against a perfect form that the digital age has begun to corrupt; brush away the datamosh and the truth beneath is yours to seize.
