Art teacher Kirsten Janssen is one of several artists featured in the Sonoma County Museum’s exhibit called “Obsession.”

Janssen’s piece, “The Length of DNA and How I Measured Up to the Moon,” which stands 8 by 10 feet, is a “kinetic sculpture of curves of thread that spin and weave and twist into a DNA-like strand by the push of a button,” she said.

The exhibit consists of pieces from private collections of Sonoma County residents. These pieces include sculptures, paintings, taxidermy and historic artifacts. For example, strands of President Lincoln’s hair and a 16th century map of Japan are on display, according to the “Obsession” flier. “It is a menagerie of work that Sonoma county residents collect,” Janssen said.

Janssen’s artwork is part of Sonoma resident Anne Hatch’s collection. Hatch owns 210 art pieces but they will not be shown at the museum.

The exhibition also features Ann Hamilton, Janssen’s former art professor from UC-Santa Barbara.

Despite having been in numerous shows, this is Janssen’s first time at the Sonoma County Museum. “I’m usually in great shows,” she said. “I show at Hosfelt gallery in San Francisco, and I am in several collections.”

Janssen’s next art exhibit is at the Yerba Buena Center for the Arts. “I have an upcoming show called ‘The Missing Peace: A Portrait of the Dalai Lama’,” she said. “It is a show of 80 artists and their perspective of the influence of him.” The show will open on Nov. 29.
