Roger Avary's first Tweet as an incarcerated man hit the Web this afternoon, four days after the writer-director checked into the Ventura County Jail to begin his one-year sentence for felony manslaughter. "The building is an imposing example of the Brutalist architectural movement," Avary wrote. "The windows are designed so as to not let too much light in." Not that he's necessarily tweeting from the jail yard, however. Avary's clean record prior to his DUI accident last year -- which killed a passenger in his vehicle -- made him eligible for work-furlough: He's out working on projects during the day, and back by curfew for a night in his cell. So for all we know he's just starting another one of his Twitterplays or describing Harvey Weinstein's office. [Twitter]
