“X Marks the Spot”

Quantitative or categorical, discrete or continuous, dependent or independent — variables allow scientists of every discipline to measure and describe the world. And variables can inspire artists. With a mixture of whimsy and seriousness, work by eight artists creatively illuminates variables gathered through personal record-keeping or scientific experimentation. Featured artists: Carrie Crane, Laurie Frick, Megan Hildebrandt, Elizabeth McClellan, Mark Nystrom, Cathryn Rowe, Francesca Samsel and Ele Willoughby.

Opening reception: 7 to 10 p.m. Saturday. Exhibit continues through Nov. 23.
