For all of the handwringing about art being inaccessible, there’s no city planning theory that has gained more traction in this century than the idea of creative people driving neighborhood revitalization.

The month-long residency program, which began last week, might actually work at creating a less sterile West Los Angeles, not least because it is supported by the powerhouse Hammer Museum, whose three-story compound anchors one end of the street. On a stretch of Westwood Ave., better known for chain sandwich shops and fluorescent interiors, the Hammer offered a half-dozen empty storefronts to local artists and makers, with the idea that even a temporary infusion would upend the retail mood of the area. If the packed opening night was any indication, this time the theory holds. Here’s what we saw.
