When the graphic designer JP Williams appeared on "The Martha Stewart Show" a few years ago with his collection of vintage twine balls, the famed hostess marveled over the fact that he viewed them as art, not just utilitarian objects. Now, for his exhibition "Little Things: A Flâneur's Finds" at Tribeca's Mondo Cane gallery, he's transformed them into art that anyone can appreciate: a family of small cast bronze sculptures that also includes facsimiles of doorstops, dried banana peels and 10 other curiosities from his extensive personal archive. "Each item was picked from off my shelves or out of my drawers because I thought other people might want to hold or touch it," says Williams, who was a founder of the esteemed design firm MW in 1993. While his first bronze made its debut last year at the now-shuttered NoHo shop Partners & Spade, the Mondo Cane exhibition is the first time he's stepped away from client work to properly showcase his own creations. "They're all about form for me, and seeing that form transcend whatever it was before," he explains. That's what art is really about, isn't it? "Little Things: A Flâneur's Finds" is at Mondo Cane, 174 Duane Street, New York, through Dec. 10.
