We asked visitors to our booth to attempt solving the puzzle while wearing a blindfold. A teacher named Christy Smith solved it in 15 minutes at the Texas Computer Education Association (TCEA) conference. At SXSWedu, high school student Matthew Hebrado did it in 25 minutes. Still not impressed? At SXSW, 12-year-old Atticus Adair pulled it off in 20 minutes!
