It wasn't the biggest or the glitziest art exhibit last year — and "big" or "glitzy" would have been completely out of place in the industrial Boynton Beach Arts District anyway — but "(Un)Common Traces," featuring the work of four members of art collective Dwelling Projects, was far and away the scrappiest and most spirited. Spread throughout three bays of the BBAD compound, the photography, video, pen-and-ink, watercolor, charcoal, and fiber assemblage drew inspiration from the artists' recent visit to Ecuador, where they spent a month immersed in the Andean nation's artistry and culture. Their work plays on themes of spirituality, nature, landscape, travel, work, and the commodity economy, overrunning boundaries and commenting one on the other. For building bridges among cultures and among South Florida arts communities, "(Un)Common Traces" was unmatched.
