Metal kinetic sculptures line one street in Milford, courtesy of two local artists \u2014 Sonny Cardinali and Mike Galullo. There is a metal robot and headless creature, which stood sentry outside Mr. Cardinali\u2019s house at Halloween time, the perfect headless horseman, and a metal fish, a spider, and a huge structure made of metal cups and metal poles that spins when the wind blows. And more. The two Milford men have been collaborating on their art for several years, and recently decided that if they wanted to display it, they needed the outdoors. Because most of these pieces need wind to complete the artistic element they were designed for \u2014 and that is to move \u2014 Mr. Cardinali got permission from his East Avenue neighbors in the Bayview Beach section of Milford to put sculptures on their front lawns. There are nine pieces on display altogether along the street. Both men have been working on their crafts for years. Mr. Galullo has been active in Milford art endeavors for years, sometimes painting as part of public art shows; he actually emerged on the public scene in Milford not as an artist but as a man who spoke out about political matters \u2014 mainly land-use issues. By profession, Mr. Galullo is a teacher at Cider Mill School in Wilton. He received his bachelor of fine arts degree from the University of Connecticut in 1981 with a major in printmaking, and then earned his teaching license through Southern Connecticut State University\u2019s teacher certification program. He received a master of arts degree in liberal studies from Wesleyan University in 2001 and taught art at East Hampton Middle School before moving over to Cider Mill School in 1998. Mr. Cardinali, who works at the Discovery Museum in Bridgeport as an exhibition technician, said he\u2019s been welding together pieces of metal for years, turning them into creatures, solar systems or whatever strikes his fancy. He is self-taught, and according to his website, twistingsteel.com, he fell into art by chance after learning how to weld in his garage. \u201cWelding small pieces together for a local manufacturer, he started seeing other shapes in the metal,\u201d the website says. \u201cHe would sit in his garage for hours, thinking up new ways to put the pieces together. After a few weeks, Sonny developed a love for art and has been creating sculpture nonstop ever since.\u201d He participates in local art exhibitions, and has developed a following for his one-of-a-kind steel designs. Mr. Cardinali finds the metal gadgets he\u2019s looking for at junkyards, metal suppliers \u2014 and pretty much anywhere else \u2014 and he starts putting them together. \u201cThe fish over there is made of a basketball hoop and a rake,\u201d he said, pointing to one of the sculptures in his front yard. Sometimes he knows what he wants to create before he starts looking for metal objects; other times he starts to collect pieces and sees where the art takes him. \u201cIt goes both ways,\u201d he said, adding that sometimes what he\u2019s envisioned actually changes shape as he builds. Mr. Cardinali also builds and restores motorcycles, so some of the sculptures are bound to have some Harley parts mixed in. Finding metal, cutting metal, bending metal, and finally welding the metal are all parts of his craft. His earlier artwork was constructed and finished with mostly rusted metal objects \u2014 that is, until Mr. Galullo, who lives a couple of streets over, suggested the art might take on another dimension if Mr. Cardinali let him paint the pieces. \u201cIt changed the whole look of them,\u201d Mr. Cardinali said. Color can even turn a piece of his friend\u2019s art that Mr. Galullo wasn\u2019t really thrilled with into his favorite. The piece called Conversation didn\u2019t appeal to Mr. Galullo at first. \u201cAs I was making it, he said he didn\u2019t like it,\u201d Mr. Cardinali recalled. But when the pieces were completed, and then Mr. Galullo painted them with a black-on-white pattern on one piece and white-on-black on the other, the opposing colors made the pieces work together in a different way. \u201cI like the relationship between the two pieces now,\u201d Mr. Galullo said. \u201cThey look like they\u2019re talking to each other.\u201d And because the tops of the pieces move in the wind, they almost seem to bow to each other as they converse. Mr. Galullo gets hold of Mr. Cardinali\u2019s creations when they are complete, studies them a bit and then decides on the color scheme. \u201cIt\u2019s like they speak to me,\u201d he said, joking. \u201cThey tell me what they want.\u201d Mr. Cardinali added, ribbing him, \u201cAnd it takes him a long time to paint them. He must be arguing with them.\u201d The two men have work in numerous private collections around Connecticut. They also have worked together on very large pieces, including one outside the Stamford Museum and Nature Center, which measures 12 feet by 16 feet. The art is all for sale, and prices range from $900 to $8,000. All the pieces may be seen in action at the Twisting Steel Productions website, twistingsteel.com.
