In the documentary Visual Acoustics: The Modernism of Julius Shulman, there is a moment when cinema meets its cousin architecture. It happens in the section on Pierre Koenig’s Case Study House No. 22. Here, the cinematographer Dante Spinotti glides, tracks, flows through the house’s glassy and boxy spaces. Pictures moving through interiors. You can see this excellent documentary as part of the Seattle Design Festival, which runs for 10 days and includes two docs tonight, Eye Over Prague (this concerns the Czech architect Jan Kaplický) and How Much Does Your Building Weigh, Mr. Foster? (the huge hole next to City Hall—that was supposed to be a Foster). The festival also celebrates SIFF’s recent engagement with serious design, the new film center in Seattle Center’s Northwest Rooms. (SIFF Film Center, Seattle Center, www.seattledesignfestival.org, 7 pm (Foster) and 9:30 pm (Prague), $10 each)
