That's the perimeter of Plastorm, the moniker that local artist and film editor Robert B. Fortney gave to his backyard studio along a North Skidmore Street alleyway between Kerby and Borthwick avenues. Less tendentiously, it's a converted shed where he toils at his graffiti-inspired paintings and multimedia works. But if you were to wander into the yard—don't do that!—you'd be forgiven for thinking it was a command center. The area is decked out with computer monitors, some of which feature images from the alley thanks to cameras mounted on the various sci-fi warriors. Two stormtroopers, Kylo Ren, a metallic owl named Bubbo, and a Darth Vader donated by a neighborhood fan guard the area, calling out to passersby either by automated motion-activated recordings or a delighted Fortney speaking through a mic.
