Scenes from Riverfest in Assembly Square

Hundreds of people flocked to Somerville’s Assembly Row to celebrate Riverfest 2013. The end of the summer party hosted food trucks, children’s activities, live music, local art, and a special exhibit highlighting steampunk.

Chris Osborne of Steampunk Lighting has been restoring and selling lighting fixtures for 40 years. Three years ago, he began focusing on steampunk lighting. “It’s the most fun I’ve had in years,’’ Osborne said.

Cash Hardy, 3, got his face painted like a cat. His mother, Lea, said they attend Riverfest every year. “It’s a good time, and the kids love it!’’ Lea Hardy said.

One artist slowly made her way through the crowds, camouflaged as an autumn tree.

This seafaring statue was no statue at all. Many participants posed for pictures with the artist once they realized he was alive.

Families waited to bounce on the multiple bounce houses set up along the Mystic River.

A couple of children tried to hit targets with footballs during Riverfest 2013.

Teá Desmond, 11, fought an elastic band while trying to stick a beanbag to a Velcro strap. Her father, Billy, said they are regular Riverfest attendees. “It brings everyone together,’’ Billy Desmond said. “Plus, what was here before? An empty field.’’

Riverfest attendees wandered around the local artist market, where local vendors displayed their wares.

Amanda Grondin of Alleeann Illustration said her art combines her love of horticulture and sculpture. She makes jewelry, mini world terrariums, and sculptures inspired by the extraterrestrial.

Melissa Grifone, an Origami Owl vendor, showed a new take on charm jewelry. Purchased charms are displayed inside a locket-type pendant rather than attached to a chain.

Bruce and Melanie Rosenbaum of ModVic Steampunk Design exhibited a mini ode to steampunk. “Assembly Row (has a lot to do with) an industrial re-imagination of the space, which fits in with steampunk,’’ Bruce Rosenbaum said.

Bruce Rosenbaum displayed one of pieces from a larger exhibit that will be displayed in Springfield museums. The display is a take on “20,000 Leagues Under the Sea’’ author Jules Verne.

Lezli Whitehouse posed in a custom-made vintage sleeveless coat with a custom blaster. The coat was designed by Cloak and Dagger Creations.

Peachpit performed live during Riverfest 2013.

Artist Dave Dawson of Scrapped and Found displayed mirrors with custom made frames. The frames incorporate recycled metals such as tin roof ceiling, radiator mesh, and old license plates into the design.

Hungry attendees waited in line at the Pasta Pot food truck during Riverfest.
