From the schlubiness of Peter Falk to the flava of Flav, everyone expresses uniqueness differently -- what's important is just to be unique. For furnishings that run the one-of-a-kind gamut, check out Tortoise.
Just expanded to a down-the-street, gallery-like 2nd location, Tortoise specializes in singular interior accessories imported regularly from the owners' birthplace of Japan; there's no binding theme, other than you won't find any of it catching crumbs in front of some other jerk's TV. On the approachable end, options include everything from traditional glazed ceramic flatwear and bowls to modernistic, custom-made plywood/Douglas Fir couches, bookshelves, and tables built so low to the ground, your vermin will assume you're acknowledging their squatters rights. More eclectic action's highlighted by dual ceramic rabbit statues (one cuddly, the other bloodmouthed toothy) and a full-sized bathtub assembled from wood (doubles as coffin -- just add hair dryer).
Periodically, Tortoise plans to showcase work from a single artist -- which could actually undermine uniqueness, if the only model of clock on sale is purchased for your nightstand, and a certain someone's neck.
