Proximities: Art in the Tree-Ring Lab

Friday, April 10, 2015

Patterns and time are hinges to both art and science.

This is apparent in the new exhibit in the University of Arizona’s Bryant Bannister Tree-Ring Building, “Marking Time to a Changing Climate,” which features work by UA’s Ellen McMahon, Thomas Saffle, Kejun Li, and Jesse Chehak.

After a quick look at Li’s prints, you might think they are images of tree rings, ones that note time in terms of decades or centuries, reflecting patterns of growth marked by fire scars and droughts. In actuality, Li’s pieces were made by dragging a credit card across a piece of glass.
