'Experiment'-Minded: Students and others crowd a hallway in the University's College of Architecture and Design Building to see last night's Cinema Guild showing of experimental "off-beat" films. Ann Arbor police stopped last week's show and seized the film "Flaming Creatures" on the grounds it is obscene. No such move took place last night. The furor resulted in a great increase in business for the Cinema Guild--four instead of the usual two showing were required to take care of the crowds. This photo was taken a few minutes prior to the 7 p.m. show which already had a "full house."
